Suppose that a random sample of size 64 is to be selected from a population with mean 40 and standard deviation 5. (a) What is the mean of the xbar sampling distribution

Answers

Answer:

Sample mean (xbar) = 40

Step-by-step explanation:

Given that :

Sample size (n) = 64

Population mean (μ) = 40

Standard deviation (σ) = 5

The sample mean is equal to the population mean according to the central limit theorem.

The sample standard deviation = standard error = ;

Standard Error = σ / √n

Standard Error = 5 / √64

Standard Error = 5 / 8

Standard Error = 0.625

Peter collected 171 marbles but lost 3/4 of them on his way home through of hole in his bag when he arrived at home now many marbles did Peter have left?​

Answers

The answers is 43 since 171 divided by 4 is 42.75. So then multiply that by 3. and subtract that from 171. and u get ur answer which is 43

The number of marbles Peter had when he arrived home was 43 marbles

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

The number of marbles Peter had on his way home = 171

The amount of marbles he lost on his way home = ( 3/4 ) th

Now , the amount of marbles Peter have left = 1 - amount of marbles he lost on his way home

The amount of marbles Peter have left = 1 - 3/4

                                                                = ( 1 / 4) th

So , The number of marbles Peter had left when he arrived home is =

Amount of marbles Peter have left x Number of marbles Peter had

The number of marbles Peter had left when he arrived home is = (1/4) x 171

= 171 / 4

= 42.75

≈ 43 marbles

Hence , the number of marbles Peter had left when he reached home is 43

A poll agency reports that 45% of teenagers aged 12-17 own smartphones. A random sample of 152 teenagers is drawn. Round your answers to four decimal places as needed. Part 1 out of 6 Find the mean The mean il ESSENEN IN

Answers

Answer:

Mean = 0.45

Standard deviation = 0.04035

Step-by-step explanation:

This is actually a very simple problem.

The question gives us the report that 45% of the teenagers in the age bracket own smartphones.

P = mean = 45%

Therefore the mean is 0.45.

I will go ahead to help you calculate the standard deviation.

√p(1-p)/n

n = 152

P = 0.45

√0.45(1-0.45)/152

= √0.45(0.55)/152

= √0.2475/152

= √ 0.001628

= 0.04035

How to graph y=12-6x

Answers

Answer:

The answer will be listed below.

Step-by-step explanation:

This equation is in y=mx+b form, so to graph this equation, take the y-intercept which would be 12. Go on your graph and make twelve on the y-axis (you can go by two's or even six's). Then take your slope which would be -6 and use rise of run which would be down 6, since it's negative, and to the right one. Keep repeating this process until you ran out of space. Draw a line between the points and you have graphed a line.

The measure of base angle of the isosceles right angle triangle is 45°.

What is a right angle triangle?

A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any angle is a right angle.

Given that,

Triangle ABC is an isosceles right angle triangle.

In an isosceles triangle, two sides are equal and corresponding angles are equal.

Let the corresponding angles are α and α.

Since, one angle of right angle isosceles triangle is 90°.

Also, the sum of angles of triangle is 180°

Implies that,

α  + α  + 90 = 180

2α  = 180 - 90

2α  = 90

α  = 45

The required value of angle α  is 45°
