b.Based on these results, estimate the probability of the event “a customer searches for aRedrose”given“a customer searches for a rose with theTea Rosefragrance”.[2]

c.What would be the appropriate Chi-square test for assessing whether there is a significant relationshipbetween the color preference and the fragrance preference in the population of all (potential) customers?[1]Place a clearXon the appropriate line below.

d.From the R output, the observed teststatistic is 40.5093. Calculate thecontribution to the test statistic from thesearches for aWhiterose withMyrrhscent.

Final Answer: ______࠵?. ࠵?࠵?࠵?࠵?______e.Based on the test results, complete the conclusion by placing a clear X on the appropriate line below.[2]At a 5% significance level, there:_X_DOES____ DOES NOTappear to be a significant relationshipbetween the color preference and the fragrance preference in the population of all (potential) customers.

Stats 250 F17 Final ~ page44.Average Salaries for Bachelor’s Degrees ~The National Association of Colleges and Employers (NACE)conducted a survey of recent graduates with only a bachelor’s degree who majored in one of three areas (group1: Business, group 2: Computer Science (CS) and group 3: Engineering). An analyst at the center wishes toassess if there are significant differences among the three majors in terms of average salaries ($) for recentgraduates with a bachelor’s degree, using a 5% significance level. Descriptive statistics and ANOVA results fromR are provided.a.State the appropriate ANOVA hypotheses for testing whether or not the major has an effect on the meansalary ($) for recent graduates with a bachelor’s degree.[2]

b.Several plots of the data could be made to help verify some ofthe assumptions. The assistant working on this study created ahistogram of average salary ($) for the 161 recent graduates witha bachelor’s degree in the sample from the three differentmajors as shown at the right.[2]Is this the appropriate histogram to examine?Place a clear X on the appropriate line.____Yes_X_ No
