Assume You Obtained a MINITAB Output and a Boxplot of Differences

Question 7

Multiple Choice

Assume you obtained a MINITAB output and a boxplot of differences between the number of fish at a depth of 5 meters and 10 meters. ​ Assume you obtained a MINITAB output and a boxplot of differences between the number of fish at a depth of 5 meters and 10 meters. ​ ​ ​ Choose the correct statement. ​ A) The boxplot of differences is approximately symmetric and does not show any outliers, so the assumption of normality is not unreasonable and we will use the paired t test. B) The boxplot of differences is approximately symmetric, but has outliers, so the assumption of normality is not unreasonable and we will use the paired t test. C) The boxplot of differences is approximately symmetric, but has outliers, so the assumption of normality is unreasonable and we cannot use the paired t test. D) The boxplot of differences is approximately symmetric and does not show any outliers, so the assumption of normality is not unreasonable and we cannot use the paired t test. ​ Assume you obtained a MINITAB output and a boxplot of differences between the number of fish at a depth of 5 meters and 10 meters. ​ ​ ​ Choose the correct statement. ​ A) The boxplot of differences is approximately symmetric and does not show any outliers, so the assumption of normality is not unreasonable and we will use the paired t test.
