F A random sample of people were asked whether they were athletic, moderately athletic (Mod), or not athletic (NotAth). Then they were tested for reaction speed. Reaction speed was measured indirectly, through reaction distance, as follows: A vertical meter stick was dropped and they caught it. The distance (in centimeters) that the stick fell is the reaction distance, and shorter distances correspond to faster reaction times. Complete parts a and b below.

Compare the medians, interquartile ranges, and shapes, and mention any potential outliers. Choose the correct answer below. A. The athletic boxplot has a much higher median and a much smaller IQ than the other two boxplots. The nat athletic boxplot is strongly skewed to the right. There is an outlier in the not athletic boxplot. OB. The medians and interquartile ranges are all similar. The not athletic boxplot is strongly skewed to the right. There are no potential outliers. OC. The athletic boxplot has a much higher median and a much smaller IQR than the other two boxplots. The moderately athletic boxplot is strongly skewed to the right. There are no potential outliers. OD. The medians and interquartile ranges are all similar. The moderately athletic boxplot is strongly skewed to the right. There is an outlier in the not athletic boxplot. b. Test the hypothesis that people with different levels of athletic ability (self-described) have different mean reaction distances, reporting the F-statistic, p-value and conclusion. Assume that the distribution of each population is close enough to Normal to satisfy the Normal condition of an ANOVA and that the sample is randomly selected. Let Hath represent the mean athletic reaction distance, let mod represent the mean moderately athletic reaction distance, and let not represent the mean not athletic reaction distance. Determine the null and alternative hypotheses. Choose the correct answer below. OA. Ho Hath #Hmod #Hnot Ha Hath Hmod Hnot OB. Ho Hath Hmod Hnot Ha Hath #Hmod #Hnot C. Ho Hath Hmod not H: At least one of the means is different from another. OD. Ho: At least one of the means is different from another.
