group down by looking only at the student interns‚ the standard deviation is smaller‚ because the individuals within this group have salaries that are less variable. The second data set isn’t better‚ it’s just less variable. Similar to the mean‚ outliers affect the standard deviation (after all‚ the formula for standard deviation includes the mean). Here’s an example: the salaries of the L.A. Lakers in the 2009–2010 season range from the highest‚ $23‚034‚375 (Kobe Bryant) down to $959‚111 (Didier

Normal: n = 27‚ which is less than n=30. We need to look at the boxplot and histogram to determine if the sample is normal. The diagram shows that the sample data is skewed to the left‚ with an outlier at 200. The sample is not normal because the diagram is not unimodal‚ symmetrical‚ and it contains an outlier. D) E) Since the p-value is less than the significance level at 0.05‚ we reject the null hypothesis and conclude that there is sufficient evidence to support the claim
