Hypothesis testing for the population mean.

A survey of BB Gaming System console video game players gave a relative rating of at least 42 from those customers that were "very satisfied".

Letting μ be the mean composite satisfaction rating for the gaming console, we find out that the test should be Ho: μ ≤ 42 versus Ha: μ > 42

In order to attempt to supply evidence supporting the claim that μ exceeds 42.

The random sample of 65 satisfaction ratings yields a sample mean of x-bar = 42.954. Assume that σ equals 2.64.

find out the value of the test statistic: [ ]

What is the rejection point at α = .10 and indicate if you would accept or reject Ho? z.10 = [ ]

What is the rejection point at α = .05 and indicate if you would accept or reject Ho? z.05 = [ ]

What is the rejection point at α = .01 and indicate if you would accept or reject Ho? z.01 = [ ]

What is the rejection point at α = .001 and indicate if you would accept or reject Ho? z.001 = [ ]

Compute the p-value: [ ]

How much evidence is there that the mean composite satisfaction rating exceeds 42? [ ]
