1. In a survey of 81 randomly selected individuals, it was found that they eat 100 days out of the year at fast-food restaurants. Is this sufficient evidence to show that this is higher than the previously found average number of days that one eats at fast-food restaurants was 85 day at 5% significance level. State the alternative hypothesis for this test. 2. If we fail to reject the null hypothesis when, in fact, it is false, we have 3. in formulating hypotheses for a statistical test of significance the alternative hypothesis is 4. The critical region of a test is 5. You are thinking of using a t procedure to test hypotheses about the mean of a population using a significance level of 0.05. The sample graph is fairly symmetric but has a few outliers
