this question below You wish to test the following claim (H) at a significance level of a = 0.02. Ho : p = 84.3 H : < 84.3 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n 74.8 and a standard deviation of SD = 9.1. 12 with mean M 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 =
