In a nationwide polls of 1,500 randomly selected u. s. residents, 77% said that they liked pizza. in a poll of 1,500 randomly selected u. s. residents one month later, 75% responded that they liked pizza. a. does the polling evidence support the claim that pizza declined in popularity over the month between polls? explain why or why not. b. using statistical terminology, precisely identify the population parameter the two polls were attempting to measure. how does a parameter differ from a statistic? c. based on the two polls, what would you say to someone who guessed that the population parameter the polls are trying to measure is really only 50%?

Your correct One can do a two-proportion test and find that the z-value for different is 1.28 (or -1.28, depending how one sets up the test).

The p-value for that is 0.20, so by most tests this is not statistically significant.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
