Exercises 1-5 refer to the sample data in the following table, which summarizes the last digits of the height cm of 300 randomly selected subjects (from data set 1 " body data"). Assume that we want to use a 0.05 significance level to test the claim that the data are from a population having the property that the last digits are all equally likely. 4-If using a 0.05 significance level to test the stated claim, find the number of degrees of freedom. 5-Given that the p-value for the hypothesis test is 0.501, what do you conclude? Does it appear that the height were obtained through measurement or that the subjects reported their heights? Last digit 0 1 2 3 4 5 6 7 8 9 Frequency 30 35 24 25 35 36 37 27 27 24
