Last week, Norma sold 80% of the peanut butter squares she baked. She sold 24 peanut
butter squares.

Answer:

since Norma sold 24 of the peanut butter squares that she baked and it is 80% of it. There is only 20% of the peanut butter squares she has baked. Leaving it to be only 6 peanut butter squares left.

This is because 24 is the 80% of 30. She had 30 in total and sold that 80% which is 24. So, therefore it leaves 6 peanut butter squares left. Making it 20% of what Norma baked.

You are employed by the Indiana Pacers to model attendance at their regular season basketball games. Paid attendance is your dependent variable, and you employ a variety of independent variables: the Pacers' current winning percentage (WINPCT), their opponents current winning percentage (VISPCT), the number of all-star votes received by the visiting team, in millions (ALLSTAR), the fraction of minutes played by foreign players on the visiting team (FOREIGN), and the number of home games for the Pacers in the next week (NEXTWEEK). Your regression output is presented below.

Select one:
a. "You are correct: a team composed entirely of foreign players would draw 503 fewer fans than a team composed entirely of domestic players."
b. "You are correct: a team composed entirely of foreign players would draw on average 503 fewer fans than a team composed entirely of domestic players."
c. "You are incorrect: my model proves that the percentage of foreign players has no effect on attendance."
d. "You are incorrect: foreign players actually increase attendance."
e. "You may or may not be correct: we have insufficient evidence in this model that foreign players decrease attendance." Clear my choice

People were polled on how many books they read the previous year. Initial survey results indicate that s= 18.1 books. Complete parts ​(a) through ​(d) below.

(a) How many subjects are needed to estimate the mean number of books read the previous year within six books with 95​%​confidence?

This 95% confidence level requires ____subjects. ​(Round up to the nearest​ subject.)

(b) How many subjects are needed to estimate the mean number of books read the previous year within three books with 95​% ​confidence?

This 95% confidence level requires _____subjects. ​(Round up to the nearest​ subject.)

(c) What effect does doubling the required accuracy have on the sample​ size?

A.Doubling the required accuracy nearly quadruples the sample size.

B.Doubling the required accuracy nearly halves the sample size.

C.Doubling the required accuracy nearly quarters the sample size.

D. Doubling the required accuracy nearly doubles the sample size.

​(d) How many subjects are needed to estimate the mean number of books read the previous year within four books with 99% confidence?

This 99% confidence level requires _____ subjects. ​(Round up to the nearest​ subject.)

This 99% confidence level requires ____subjects. ​(Round up to the nearest​subject.)

Compare this result to part (a). How does increasing the level of confidence in the estimate affect sample​ size? Why is this​reasonable?

A. Increasing the level of confidence increases the sample size required. For a fixed margin of​ error, greater confidence can be achieved with a smaller sample size.

B. Increasing the level of confidence decreases the sample size required. For a fixed margin of​ error, greater confidence can be achieved with a larger sample size.

C. Increasing the level of confidence decreases the sample size required. For a fixed margin of​ error, greater confidence can be achieved with a smaller sample size.

D. Increasing the level of confidence increases the sample size required. For a fixed margin of​ error, greater confidence can be achieved with a larger sample size.
