Question: The tail length in millimeters (x1) and wing lengths in millimeters (x2) for 45 male hook- billed kites are given in t6-11.dat. Test for equality of mean vectors for the populations of

male and female hook-billed kites.

1. Check the male data for univariate normality (histograms, boxplots, and Q-Q plots.
2. Check the male data for outliers: post your scatterplot pairs and a table of values to
   check for outliers. Describe the four ways we check for outliers.
3. Check the male data for multivariate normality by posting a Chi-Square plot.
4. Use Box's M-test to test for equality of covariances. Set _ = 0:05. Write your null
   and alternative hypothesis, give your test statistic, C, and critical value, state your
   conclusion.
5. Test the Hypothesis for equality of mean vectors for the two populations. Write your
   null and alternative hypothesis, give your T2 test statistic, critical value, and decision.
6. Give the Simultaneous Confidence intervals and interpret.
7. Give the Bonferroni Confidence intervals and interpret.
8. BONUS: create a scatterplot of male and female data and color males blue and females

red. See lizard data on p.335.
