(a)Here we want to test . Hence the appropriate hypothesis from the given options is (B) . It is a right tailed test.
(b)Given that
Let .
The test statistic is given by, .
The value of the test statistic is =2.70
(c) Since the given test is right tailed test and the test statistics follows standard normal distribution the P value of the test is given by,
(d) What is the result of this hypothesis test?
Given that the significance level of the test , and P value is 0.0035. Since P value is less than the significance level we reject the null hypothesis and hence . Hence the correct option is (c) Reject the null hypothesis because there is sufficient evidence to conclude that .
