Question

You wish to test the following claim ( H a ) at a significance level of α = 0.02 .

H o : μ = 65.6

H a : μ > 65.6

You believe the population is normally distributed and you know the standard deviation is σ = 19.8 . You obtain a sample mean of M = 70.7 for a sample of size n = 29 . What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value

please do it step by step

thanks
