Probability
For the sake of argument, we begin by assuming that u equals 42, and we then attempt to use the sample to contradict this assumption in favor of the conclusion that u exceeds 42. Recall that the mean of the sample of 65 satisfaction ratings is 42.95, and assume that o, the standard deviation of the population of all satisfaction ratings, is known to be 2.64. a Consider the sampling distribution of i for random samples of 65 customer satisfaction ratings. Use the properties of this sampling distribution to find the probability of observing a sample mean greater than or equal to 42.95 when we assume that u equals 42.
