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. 1-what are the null and alternative hypotheses corresponding to the stated claim? 2-when testing the claim in Exercise 1, what are the observed and expected frequencies for the last digit of 7? 3-is the hypothesis test left-tailed, right-taled, or two-tailed? 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

1-what are the null and alternative hypotheses corresponding to the stated claim?
2-when testing the claim in Exercise 1, what are the observed and expected frequencies for the last digit of 7?
3-is the hypothesis test left-tailed, right-taled, or two-tailed?
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 |
