You wish to test the following claim at a significance level of a = : 0.01. Ho : p = 87.2 H < 87.2 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size 64 with mean 85.2 and a standard deviation of 11.7. What is the test statistic for this sample? (Report answer accurate to 3 decimal places.) What is the pvalue for this sample? (Report answer accurate to 4 decimal places.) This test statistic leads to a decision to reject the null accept the null O fail to reject the null As such, the final conclusion is that there is sufficient evidence to conclude that the population mean is equal to 87.2. there is not sufficient evidence to conclude that the population mean is equal to 87.2. there is sufficient evidence to conclude that the population mean is less than 87.2. there is not sufficient evidence to conclude that the population mean is less than 87.2.
