Can you please help me solve these problems

You wish to test the following claim (Ha) at a significance level of a = 0.001. Ho: H = 77.9 Ha: H > 77.9 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 13 with mean a - 87.1 and a standard deviation of s = 9.2. You may want to use Excel One Mean Calculator available in the Course. a. What is the p-value for this test? (Report answer accurate to four decimal places.) p-value = b. The p-value is... O less than (or equal to) a greater than a c. This p-value leads to a decision to... O reject the null O accept the null O fail to reject the null d. As such, the final conclusion is that... The sample data support the claim that the population mean is greater than 77.9. There is not sufficient sample evidence to support the claim that the population mean is greater than 77.9. Question Help: Video Submit
