You wish to test the following claim (Ha) at a significance level of =0.01. Ho:=82.4Ho:=82.4 Ha:82.4Ha:82.4 You believe the population is normally distributed and you know the standard deviation is =5.5. You obtain a sample mean of M=85.2 for a sample of size n=19. 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...

• less than (or equal to)
• greater than

This test statistic leads to a decision to...

• reject the null
• accept the null
• fail to reject the null

As such, the final conclusion is that...

• There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 82.4.
• There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 82.4.
• The sample data support the claim that the population mean is not equal to 82.4.
• There is not sufficient sample evidence to support the claim that the population mean is not equal to 82.4.
