The accompanying data shows a sample of pulse rates (beats per minute) that were categorized with two factors, age bracket (years) and gender. The data were used to illustrate the use of two-way ANOVA. How are the results affected in each of the following cases? a. The same constant is added to each sample value. b. Each sample value is multiplied by the same nonzero constant. c. The format of the table is transposed so that the row and column factors are interchanged. d. The first sample value in the first cell is changed so that it becomes an outlier. E Click the icon to view the pulse rate data. O D. The test statistic will change, but the P-value will not change because increasing all values by a similar amount will not change the variance of the sample. b. Choose the correct answer below. - X Pulse Rate (beats per minute) O A. The P-value will change because the mean w the sample. O B. The test statistic will change because both the OC.

The test statistic and P-value will not change. c. Choose the correct answer below. O A. The test statistic and P-value will not change. O B. The test statistic will be negative one times th ot change. Print Done OC. The test statistic will change because both the O D. The P-value will be one minus the previous P d. Choose the correct answer below. O A. The P-value will be approximately one minus the previous P-value. The test statistic will be approximately negative one times the previous test statistic. O B. The P-value and mean will only change by a very small amount, because an ANOVA is robust against outliers and a single value cannot dramatically change the results. OC. Both the test statistic and P-value will most likely change because outliers can dramatically affect and change the results of an ANOVA. O D. The test statistic and P-value will not change.
