Question

A student would like to assess whether the mean amount of money spent on books during the 2016-2017 school year is equal for all students in each of the four class ranks at California University (1: Freshmen, 2: Sophomores, 3: Juniors, 4: Seniors). To conduct this study, the student took a large random sample of students at California University and recorded for each student the total amount of money spent on books during the 2016-2017 school year and the class rank. The student has provided you with the ANOVA R output, the student would like to use a 5% significance level and would like your help in making sense out of it. Question 7 Subquestions 7.a 2 point(s) Joseph, the student who conducted this study, has watched tutorials on how to run an ANOVA analysis using R. He is a bit puzzled by the ouput produced from Tukey's procedure because it is showing only pairwise comparisons where the difference in the population mean amount spent on books are not statistically significant. He is convinced that he has made a computational error when running ANOVA on R. Please review the results that Joseph has provided (both ANOVA table and Tukey's output), and write a short email explaining to him why the provided Tukey's output is correct. Make sure to use particular numerical output to justify your answer.

You have data on birth weights and a number of child, mother,
and family characteristics. In particular, you are interested in
the relationship between birth weight in ounces (bwght) and the sex
of the child (male = 1 if baby is male and = 0 if baby is female),
the number of years of mother’s education (motheduc), and family
income in $1000s (faminc). An “l” prefix indicates the natural log
of the variable. For example, lbwght is log(bwght).
The general...
