Mean composite satisfaction rating

Reference no: EM1318930

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 that the test should be H_o: μ ≤ 42 versus H_a: μ > 42

In order to attempt to provide 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.

Calculate the value of the test statistic:

What is the rejection point at α = .10 and indicate if you would accept or reject H_o? z_.10 =

What is the rejection point at α = .05 and indicate if you would accept or reject H_o? z_.05 =

What is the rejection point at α = .01 and indicate if you would accept or reject H_o? z_.01 =

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

Calculate the p-value:

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