You wish to test the following claim at a significance level of a : 0.01. Hozp:87.2 H1:p.< 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 p-value for this sample? (Report answer accurate to 4 decimal places.) This test statistic leads to a decision to O reject the null O accept the null O fail to reject the null As such, the final conclusion is that O there is sufficient evidence to conclude that the population mean is equal to 87.2. O there is not sufficient evidence to conclude that the population mean is equal to 87.2. O there is sufficient evidence to conclude that the population mean is less than 87.2. O there is not sufficient evidence to conclude that the population mean is less than 87.2.
