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 Ho: μ ≤ 42 versus Ha: 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 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 =
Calculate the p-value:
How much evidence is there that the mean composite satisfaction rating exceeds 42?
