Main data regarding hypothesis test

Reference no: EM13109676

Problem-1:

You want to prove that a population mean is not 7. Data is ratio and a large sample size will be used (n = 225). When the sample is done the sample mean is computed to be 7.2 and the sample standard deviation is 1.5. Test the hypothesis using an alpha of 5%. Use formal hypothesis testing and compute the p-value.

Problem-2:

An associate asks for your help in deciphering the following Anova table, indicating that a test of means was performed. Unfortunately the person leaves before you can get any further explanation or detail, but you know the results must be presented before senior staff within twenty minutes!

Use the formal 5-step hypothesis testing model to describe the test.
