In order to determine whether the selling prices of homes included in the random sample are normally distributed, the statistician divides the data into 6 classes of equal size and records the number of observations in each class. She then performs a chi-square goodness-of-fit test for normal distribution. The results are summarized in the table. 1. Complete the five step hypothesis Chi Square Goodness of fit test at level of significance 0.05. What is your decision? 2. What is your decision if you conducted the hypothesis test at level of significance 0.10? 3. At what significance level would your decision change?
