The following three independent random samples are obtained from three normally distributed populations. The (dependent) numerical variable being compared is starting hourly wage, and the groups are the types of position (internship, co-op, work study). Group 1: Internship Group 2: Co-op Group 3: Work Study 12.25 13 12.5 11.5 14 15 9.25 10.5 10.25 10 13.75 11.75 10.75 12.5 10.75 11 14.75 13 11 12.5 13 13 10.25 12.25 12.5 13.25 11 Use Exel to conduct a one-way ANOVA to determine if the group means are equal using α=0.01. Create a side-by-side boxplot in Excel for these data. Use that and the numerical summary of sample data to answer the following questions. Compute the Highest StandardDeviation/Smallest Standard = _________ (Rounded to 2 decimal places) ANOVA summary statistics: The F test statistic = _____- (Rounded to 3 decimal places) The p-value = _______ (Rounded to 4 decimal places)
