You wish to test the following claim (Hₐ) at a significance level of α=0.02.
H₀: μ=62.2 Hₐ: μ≠62.2
You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 91 with mean M = 58.8 and a standard deviation of SD = 12.1.
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... - less than (or equal to) α - greater than α
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 62.2. - There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 62.2. - The sample data support the claim that the population mean is not equal to 62.2. - There is not sufficient sample evidence to support the claim that the population mean is not equal to 62.2.
