Answers

Answer: so a can be -2 and b can be 6, note that there are many combinations since u can factor all types of stuff out including fractions

Step-by-step explanation:

a(bx+3) basically is just factoring out a random common factor between -12x and -18

Answers

This question is incomplete, the complete question is;

Condé Nast Traveler conducts an annual survey in which readers rate their favorite cruise ship. All ships are rated on a 100-point scale, with higher values indicating better service.

A sample of 37 ships that carry fewer than 500 passengers resulted in an average rating of 85.36, and a sample of 44 ships that carry 500 or more passengers provided an average rating of 81.40.

Assume that the population standard deviation is 4.55 for ships that carry fewer than 500 passengers and 3.97 for ships that carry 500 or more passengers. What is the value of the test statistic? Round your all answers to two decimal places.

Answer:

value of the test statistic is 4.13

Step-by-step explanation:

Given the data in the question;

fewer than 500 passengers                           more than 500 passengers

n₁ = 37                                                               n₂ = 44

x'₁ = 85.36                                                         x'₂ = 81.40

s₁ = 4.55                                                            s₂ = 3.97

Now, to get the test statistics, we use the following formula;

z = (x'₁ - x'₂) / √( [tex]\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2}[/tex] )

we substitute

z = ( 85.36 - 81.40 ) / √( [tex]\frac{(4.55)^2}{37} + \frac{(3.97)^2}{44}[/tex] )

z = 3.96 / √( [tex]\frac{20.7025}{37} + \frac{15.7609}{44}[/tex] )

z = 3.96 / √( 0.5595 + 0.3582 )

z = 3.96 / √0.9177

z = 3.96 / 0.957966596

z = 4.1337 ≈ 4.13

Therefore, value of the test statistic is 4.13

Change 10 miles per hour to meters per second (hint: you'll need to
change from miles to kilometers, then change kilometers to meters)


how do i do this work shown!!

Answers

Answer:

10 miles per hour = 0.1862 meter per second

Step-by-step explanation:

Given

Speed in miles per hour = 10 miles per hour

As we know

1 mile = 1609.34 meters

and 1 hour  = 24*60 *60 seconds

Thus, 10 miles per hour in meter per second would be

10 * 1609.34/24*60 *60

= 0.1862 meter per second

You measure 20 turtles' weights, and find they have a mean weight of 45 ounces. Assume the population standard deviation is 11.5 ounces. Based on this, what is the maximal margin of error associated with a 90% confidence interval for the true population mean turtle weight. Give your answer as a decimal, to two places

Answers

Answer: the maximal margin of error associated with a 90% confidence interval for the true population mean turtle weight = 4.23

Step-by-step explanation:

Formula for margin of error : [tex]E=\dfrac{z^*\times (Population\ standard\ deviation)}{\sqrt{Sample\ size}}[/tex]

, where z* = Critical z-value.

Given: population standard deviation = 11.5 ounces

Sample size = 20

Z value for 90% confidence level = 1.645

margin of error (E) = [tex]\dfrac{1.645\times11.5}{\sqrt{20}}[/tex]

[tex]\approx4.23[/tex]

Hence, the maximal margin of error associated with a 90% confidence interval for the true population mean turtle weight = 4.23

Which has a negative slope

For the first function (Gift card), we have the following observation.

As x increases from 0, 1, 2 and then 3

The values of y keep reducing

This means that the gift card function has a negative slope

For the second function (calculator rental)

What is the point estimate of the population variance (to nearest whole number)? b. Provide a confidence interval estimate of the population variance (to nearest whole number). ( , ) c. Provide a confidence interval estimate of the population standard deviation (to 1 decima

Answers

Answer:

Step-by-step explanation:

a) The point estimate of the population variance is 900 (rooms squared).

b) The 90% confidence interval estimate of the population variance is approximately (486, 1706) (rooms squared).

c) The 90% confidence interval estimate of the population standard deviation is approximately (22.0, 41.3) rooms.

a. The point estimate of the population variance can be calculated using the formula:

Point estimate of population variance = Sample standard deviation squared

= (30 rooms)²

= 900 rooms²

Therefore, the point estimate of the population variance is 900 (rooms squared).

b. To calculate the 90% confidence interval estimate of the population variance, we need to use the Chi-Square distribution.

The formula for the confidence interval of the population variance is:

Lower bound: (n-1)*sample variance / Chi-Square upper critical value

Upper bound: (n-1)*sample variance / Chi-Square lower critical value

Since we are interested in a 90% confidence interval, the Chi-Square critical values for the upper and lower tails with (n-1) degrees of freedom are 8.907 and 32.852, respectively.

Plugging in the values, we have:

Lower bound: (20-1)*900 / 32.852

≈ 486

Upper bound: (20-1)*900 / 8.907

≈ 1706

Therefore, the 90% confidence interval estimate of the population variance is approximately (486, 1706) (rooms squared).

c. To calculate the 90% confidence interval estimate of the population standard deviation, we take the square root of the lower and upper bounds of the confidence interval for the variance.

Square root of the lower bound: √486

≈ 22.0

Square root of the upper bound: √1706

≈ 41.3

Therefore, the 90% confidence interval estimate of the population standard deviation is approximately (22.0, 41.3) rooms.

A study followed for 10 years a sample of 82,695 middle-aged men with no prior history of heart failure living in California. The daily number of minutes spent being sedentary (seated) was recorded in diaries and reported on regularly administered questionnaires. During the course of the study, a total of 3,473 men experienced heart failures. Participants with high sedentary time and low sedentary times were compared. The proportion experiencing a heart failure was higher in the group of men spending more time being sedentary.
This study is an example of:_________
a. longitudinal cohort study
b. case-control observational study
c. voluntary response sample or anecdotal data
d. completely randomized experiment
e. matched pairs / repeated measures experiment
f. cross-sectional sample survey
g. census (population data)

Answers

Answer:

f. cross-sectional sample survey

Step-by-step explanation:

- longitudinal cohort study is when the group of subjects that comprises the cohort is chosen based on a disease or injury and is then monitored over time at routine intervals. In this question, it's not the case as the sample of men were just picked and studied with no special group or cohort.

- If it was case-control observational study, the research would have started with identifying those who have heart failure and those who don't have heart failure but it wasn't the case and thus this is not correct.

- If this was voluntary response sample, it means the men would have been self chosen which means they volunteered to be part of the study if it was of interest to them. But this is not the case here.

- If it was completely randomized experiment, it means that the people sampled would have been randomly assigned to different treatments which was not so in this question.

- If it were to be match pairs experiment, it means the men sampled would be grouped into pairs and each pair will be assigned different treatments which didn't happen in this question.

- If it were to be cross-sectional sample survey, it means that data will be collected from a population of interest to make inferences from that population at a point in time. That is the case here because data about sedentary time or less was taken and compared to know the effect it had on heart failure.

- If it were census, it will just be about getting the size of the population without making inquiries about sedentary time.
