A survey asks a random sample of 2500 adults in California if they support an increase in the state sales tax from 7.50% to 7.75%, with the additional revenue going to education. Let Y denote the number in the sample that say they support the increase. Suppose that 30% of all adults in California support the increase. The mean of Y is:

Step-by-step explanation:

Given

Sample Size = 2500

Percentage = 30%

Required

Calculate Mean of Y

Mean or Expected Value is calculated as thus;

Where E(Y) represents the mean

n represents the sample size (or population)

p represents the success probability

%

So,

Hence, the mean value of Y is 750

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

d. is the correct answer
