Use technology and a t-test to test the clam about the population mean p at the given level of significance a using the given sample statistics. Assume the Claim mu > 70, a=0 10 Sample statistics x = 70.4, s = 3.7, n = 27 What are the mill and alternative hypotheses? Choose the correct answer below What is the value of the standardized test statistic.

Solution

1) Option A

2) Standardised test statistic:

Mean difference = 0

p value one tailed =0.5

As p >0.05 acceptnull hypothesis
