Conduct the hypothesis test using these results. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. Identify the test statistic: (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim: Choose the correct answers in parentheses. (Reject/Fail to reject) H0. There is not (sufficient/not sufficient) evidence to support the claim that the sample is from a population with a mean less than 4.00 Mbps.
