Movie critics claim that 68% of adults and 79% of teenagers would recommend seeing the newest action movie. Suppose a random sample of 43 adults and 52 teenagers is selected. Let Pa and be the sample proportions of
adult and teenage moviegoers, respectively, who would recommend this movie.
Which of the following is the correct calculation and interpretation of the standard deviation of the sampling
distribution of PA-P?

okay wait before i answer, is this for your points on a graph?

the square root of what number? if you add that, then someone will probably answer the question.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

i think the answer would be c
