Past data has shown that the regression line relating the final exam score and the midterm exam score for students who take statistics from a certain professor is

final exam = 50 + 0.5 × midterm

One interpretation of the slope is:

A)

a student who scored 0 on the midterm would be predicted to score 50 on the final exam.

B)

a student who scored 0 on the final exam would be predicted to score 50 on the midterm exam.

C)

a student who scored 2 points higher than another student on the midterm would be predicted to score 1 point higher than the other student on the final exam.

D)

none of the above are an interpretation of the slope.

## Excel file, to test three hypotheses hidden in the conversation above.

Use data from JSMCase1 Excel file, to test three hypotheses hidden in the conversation above. Use regression analysis to investigate the relationship between age of a student, Internet usage of a student and performance of a student in an assessment of statistical knowledge and skills.

Prince Mean Chaser, Princess Age and Princess I-net have hired you to help them and they have agreed to pay you 1000 dollars if you help honestly settle their dispute with their daddy. They do not want to win for the sake of winning by any means necessary, they want you to discover the honest truth about how reasonable their beliefs are. Which of their beliefs can be supported with 95% confidence? Which of their beliefs can be supported with 99% confidence?

Discuss your findings. Use scatter diagrams, correlation coefficient r and the regression procedure to honestly settle the dispute in the royal family about the relationship between age and performance in business statistics and Internet usage and performance in business statistics.

## Determine whether the statement below makes sense or does not make sense, and explain your reasoning.

Determine whether the statement below makes sense or does not make​ sense, and explain your reasoning.

A survey problem must present the information in exactly the same order in which I determine cardinalities from innermost to outermost region.

A.

The statement makes sense. Since cardinalities are determined from innermost to outermost​ region, it is necessary to present the information in that order.

B.

The statement does not make sense. The order in which the information is presented does not​ matter, although cardinalities are determined in order from innermost to outermost region.

C.

The statement does not make sense. There is no particular order in which to determine cardinalities.

## Say that you have a sample mean of 44 in a study. (a) Estimate the corresponding population mew using point estimation.

Say that you have a sample mean of 44 in a study.

(a) Estimate the corresponding population mew using point estimation.

(b) What would a confidence interval for this tell you?

(c) Why is computing a confidence interval better than using a point estimate?

(d) What is the difference between reporting an estimate of using a margin of error versus using a confidence interval?
