Check that we can use the normal distribution to approximate the distribution of the sample statistic(the sample proportion). To be approximately normal, check . np = _______ nq = _______ State hypotheses: HO: Ha: State the Type I error for the hypothesis test within the context of this problem.
Suppose a survey of all franchises nationwide reveals that 82% of the customers responded that their service was ABOVE AVERAGE. We would like to test the claim that the proportion of local customers who responded that their service was above average is more than 82%.
Use the provided sample of 100 local customers to conduct a hypothesis test at the .08 level of significance to test the claim that the population proportion of local customers who responded that their service was above average is more than the national proportion (82%).
