    The Video Game Satisfaction Rating Case

    Please help with the following problem.

    Recall that "very satisfied" customers give the XYZ-Box video game system a rating that is at least 42. Suppose that the manufacturer of the XYZ- Box wishes to use the random sample of 65 satisfaction ratings to provide evidence supporting the claim that the mean composite satisfaction rating for the XYZ-Box exceeds 42.

    A. Letting /u represent the mean composite satisfaction rating for the XYZ- Box, set up the null and alternative hypotheses needed if we wish to attempt to provide evidence supporting the claim that /u exceeds 42.

    Null hypothesis H0: Mean composite satisfaction rating for the XYZ-Box is equal to 42.
    Alternative hypothesis H1: Mean composite satisfaction rating for the XYZ-Box is greater than 42.

    Symbolically the null and alternative hypothesis can be expressed as follows:
    H0: μ = 42; H1: μ > 42, ...
