Why is the answer 1.37 and not 1.32. I did this myself:
Homework Answers
Below are the null and alternative Hypothesis,
Null Hypothesis: p = 0.33
Alternative Hypothesis: p > 0.33
Rejection Region
This is right tailed test, for α = 0.05
Critical value of z is 1.645.
Hence reject H0 if z > 1.645
Test statistic,
z = (pcap - p)/sqrt(p*(1-p)/n)
z = (0.4 - 0.33)/sqrt(0.33*(1-0.33)/85)
z = 1.37
Hence Option E is correct.

Suppose a random sample of 100 observations from a binomial population gives a value of p = 0.45 and you wish to test the null hypothesis that the population parameter p is equal to 0.40 against the alternative hypothesis that p is greater than 0.40. Complete parts a through c. a. Noting that p = 0.45, what does your intuition tell you? Does the value of p appear to contradict the null hypothesis? O A. Yes, because p satisfies Hg:p>0.40...
