Complete question is;

About 130,000 high school students took the AP Statistics exam in 2010. The free-response section of the exam consisted of five open-ended problems and an investigative task. Each free-response question is scored on a 0 to 4 scale (with 4 being the best). For one of the problems, a random sample of 30 student papers yielded the scores that are graphed in the dot plot attached. The mean score for this sample is x¯ = 1.267 and the standard deviation is s = 1.230.

(a) Find and interpret the standard error of the mean.

(b) Construct and interpret a 99% confidence interval to estimate the mean score on this question. Use the four-step process.

Answer:

A) SOE = 0.225

The interpretation of this is that: if a sample size of 30 was taken, the difference between a sample mean score and a population mean score will be an average of 0.225

B) CI = (0.648, 1.886)

The interpretation of this is that;

We are 99% confident that that interval (0.648, 1.886) captures the true mean score of the AP Statistics exam in 2010

Step-by-step explanation:

A) We are given;

sample mean; x¯ = 1.267

Sample standard deviation; s = 1.230

Sample size; n = 30

Formula for standard error of the mean is;

SOE = s/√n

SOE = 1.23/√30

SOE = 0.225

The interpretation of this is that: if a sample size of 30 was taken, the difference between a sample mean score and a population mean score will be an average of 0.225.

B) we have a sample size of n = 30.

Thus;

DF = 30 - 1 = 29

We want to do a 99% Confidence interval.

From the attached t-table, we can see that critical t-value for DF = 29 and CL of 99%, we have t = 2.756

Formula for CI is;

CI = x¯ ± t(s/√n)

CI = 1.267 ± 2.756(1.23/√30)

CI = 1.267 ± 0.619

CI = (0.648,1.886)

The interpretation of this is that;

We are 99% confident that that interval (0.648, 1.886) captures the true mean score of the AP Statistics exam in 2010.

Answer:

the 3rd answer

Step-by-step explanation:

mean is the average and can be calculated by adding the scores and then dividing by the total number of scores.

for this take the total number of childrena and divide by the number of families which should give 3.5.

median is the middle number when the scores are put in order.

an easy way to find it from this data set is to just add the number of families from top down and bottom up and seeing where they meet which should be 3.

mode is the number that occurs the most in a data set.

for this data set it would be where the greatest number for number of families is which is 3 as there is 82 families.

Answer:

Quadrant IV

Step-by-step explanation:

Given

[tex]\theta = -405^\circ[/tex]

Required

The quadrant of the terminal side

To do this, we simply rotate the given angle in a clockwise direction.

A complete rotation is [tex]-360^\circ[/tex]

So, we have:

[tex]\theta = -405^\circ[/tex]

[tex]\theta = -360^\circ -45^\circ[/tex]

Remove the complete rotation

[tex]\theta = -45^\circ[/tex]

When [tex]45^\circ[/tex] is rotated in the clockwise direction, it stops at the 4th quadrant.

Hence, the terminal side falls in the quadrant IV

Using translation concepts, the graph that shows the function g(x) = 3|x| is graph B.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

Function g(x) = 3|x| is a vertical stretch of 3 units of function f(x) = |x|, that is, they keep the same vertex at (0,0), just graph g is stretched, passing at (1,3) instead of (1,1) for example, hence graph B is correct.
