The approximate sample proportion is
which means that
% of the readers surveyed do not use e-readers.
Answers
Answer:
The correct answer to this is 200 and 34.90%
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 3000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 3000, so we can write it down as 100%=3000.
4. We know, that x% equals 1046 of the output value, so we can write it down as x%=1046.
5. Now we have two simple equations:
1) 100%=3000
2) x%=1046
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=3000/1046
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 1046 is what percent of 3000
100%/x%=3000/1046
(100/x)*x=(3000/1046)*x - we multiply both sides of the equation by x
100=2.868068833652*x - we divide both sides of the equation by (2.868068833652) to get x
100/2.868068833652=x
34.866666666667=x
x=34.866666666667
now we have:
1046 is 34.866666666667% of 3000
Sample proportion = 0.65
And, The percentage of the sample proportion = 65%
The percentage of the readers surveyed do not use e-readers = 35%
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given sample size is,
'n' =3000
Of the 3,000 readers surveyed, 1,954 said they read books on an e-reader.
Hence, The probability that The readers surveyed use e-readers sample proportion is,
p = 1954 / 3000
p = 0.6513
Hence, The percentage of the sample proportion is, 65%
And, The readers surveyed do not use e-readers is,
q = 1 - p
q = 1 - 0.651
q = 0.349
Thus, Sample proportion = 0.65
And, The percentage of the sample proportion = 65%
The percentage of the readers surveyed do not use e-readers = 35%

Question Help The mean finish time for a yearly amateur auto race was 185.64 minutes with a standard deviation of 0.314 minute. The winning car, driven by Sam, finished in 185.29 minutes. The previous year's race had a mean finishing time of 110.3 with a standard deviation of 0.129 minute. The winning car that year, driven by Rita, finished in 110.02 minutes. Find their respective z-scores. Who had the more convincing victory?
Answers
Answer:
Sam has the more convincing victory with a greater Zscore value
Step-by-step explanation:
Given that :
Year 1:
Mean finish time (m) = 185.64
Standard deviation (s) = 0.314
Sam's time (x1) = 185.29
Year 2:
Mean finish time (m) = 110.3
Standard deviation (s) = 0.129
Rita's time (x1) = 110.02
Zscore = (x - mean) / standard deviation
Sam's Zscore :
(185.29 - 185.64) / 0.314
= - 0.35 / 0.314
= −1.114649
= - 1.115
Rita's Zscore :
(110.02 - 110.3) / 0.129
= - 0.28 / 0.129
= −2.170542
= - 2.171
Sam has the more convincing victory with a greater Zscore value
