Question
You wish to test the following claim (Ha) at a significance level of a 0.001. %3D H.:µ = 87.8 Ha:u + 87.8 You believe the population is normally distributed, but you do not know the standard deviation. You obtain the following sample of data: data 127.6 82.1 128.5 127.6 97.1 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 greater than a This test statistic leads to a decision to... O eject the null 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 87.8. O There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 87.8. O The sample data support the claim that the population mean is not equal to 87.8. O There is not sufficient sample evidence to support the claim that the population mean is not equal to 87.8.
