Suppose that the amount of time that students spend studying in the library in one sitting is normally distributed with mean 41 minutes and standard deviation 18 minutes. A researcher observed 41 students who entered the library to study. Round all answers to 4 decimal places where possible. The top 10% of the total study time for groups of 41 students will be given a sticker that says "Great dedication". What is the least total time that a group can study and still receive a sticker?

How does the pitch when striding of Aquarius remigis, the common water strider, vary with sexual maturity? Suppose that researchers interested in this question collected three simple random samples of ten water striders each, one sample for each level of sexual maturity, and measured each strider's degree of pitch when striding. For each maturity level, the table provides the mean, x, and standard deviation, s, for the pitch measurements collected along with each sample size, n. Maturity S Level Newborn 10.30 4.22 10 Juvenile 8.32 5.28 10 Adult 7.47 3.78 10 Use software to run a one-way analysis of variance, ANOVA. Report the ANOVA F-statistic to two decimal places. F = Report the P-value of your F-statistic to three decimal places.
