Chapter 13.2, Problem 11E
Four different paints are advertised as having the same drying time. To check the manufacturer’s claims. five samples were tested for each of the paints. The time in minutes until the paint was dry enough for a second coat to be applied was recorded. The following data were obtained.
| Paint 1 | Paint 2 | Paint 3 | Paint 4 |
| 128 | 144 | 133 | 150 |
| 137 | 133 | 143 | 142 |
| 135 | 142 | 137 | 135 |
| 124 | 146 | 136 | 140 |
| 141 | 130 | 131 | 153 |
At the α = .05 level of significance, test to see whether the mean drying time is the same for each type of paint.

31% of all pygmy softshell tortoises have stripes on their shells. A herpetologist in Cititon collects a sample of 28 pygmy softshell tortoises and finds that 8 of them have stripes on their shells. Is there enough evidence to conclude, at a significance of alpha = 0.05, that the proportion of pygmy softshell tortoises in Cititon with stripes on their shells is less than 31%? What is the claim? What is the null hypothesis? What is the alternative hypothesis? What is the test statistic? What is/are the critical value(s)? Do we reject the null hypothesis? What conclusion do we draw? What is the P-value for the problem above?
Dr. Romanoff reported the following in a journal: “F (5, 106) = 10.09, p = .04.”
