Suppose a random sample of 100 observations from a binomial population gives a value of ModifyingAbove p with caretequals0.76 and you wish to test the null hypothesis that the population parameter p is equal to 0.70 against the alternative hypothesis that p is greater than 0.70.
a) nothing that p = .63, what does your intuition tell you? does the value of p appear to contradict the null hypothesis?
b) use the large-sample z-test to test H0: p = .70 against the alternative hypothesis, Ha: p < 70. Use a = .05. How do the test results compare with your intuitive decision from part A?
c) find and interpret the observed significance level of the test you conducted in part B.
