You wish to test the following claim (Ha) at a significance level of a = 0.005. H,:µ = 88.4 Ha:u + 88.4 You believe the population is normally distributed and you know the standard deviation is o = 12.9 . You obtain a sample mean of M = 83.7 for a sample of size n = 51. 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 = The p-value is. O less than (or equal to) a O greater than a 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 warrant rejection of the claim that the population mean is not equal to 88.4. O There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 88.4. O The sample data support the claim that the population mean is not equal to 88.4. O There is not sufficient sample evidence to support the claim that the population mean is not equal to 88.4.
