Expert Answer

Step 1

It is given that, p0 is 0.41, the sample size n is 210.

Step 2

For np0(1–p0):

np,(1-Po) 210x 0.41(1 - 0.41) -50.799 >10

Step 3

Because np0(1–p0) = 50.799>10, the sample size is less than 5% of the population size, and the sample can be reasonably assumed to be random the requirements for testing the hypothesis are satisfied.

State the appropriate hypothesis:

Null hypothesis:

H0 : p0 = 0.41
