Question 1047236

a.	Are the requirements met to run a test like this? n > 30
b.	What are the hypotheses for this test?
c.	Compute the test statistic and the p-value for this test.
d.	What is your conclusion at the 0.02 level of significance
H0: p = .75 
H1: p < .75 claim 
sample proportion = p-hat = 85/120 = 0.71 
test stat:: z(0.71) = {{{(0.71-0.75)/sqrt((0.75*0.25)/120)}}} = -.04/.0395 = -1.0119
p-value = .1558
.1558 > .05
evidence does not support claim  the population proportion of all high school students
 that have watched at least one episode is less than 75% at the 0.05 level of significance.
