4.105 INDEX FINGER MUSCLE FATIGUE AND PISTOLFIRING. Refer to the Human Factors (November 2019) study ofthe effects of finger strength and muscle fatigue on the ability toshoot a pistol, Exercise 2.80 (p. 86). Recall that musclestrength was measured (in Newtons) by the maximum voluntaryisometric contraction (MVIC) of the index finger. Theresearchers found that when at rest, expert male shooters have amean MVIC of 160.3 N and a standard deviation of 19.6 N.However, after repeated shooting sessions, the expert shootershave a mean MVIC of 133.5 N and a standard deviation of 19.6N. Assume that the distribution of MVIC strength scores in bothscenarios is approximately normal.a. When at rest, what is the probability that an expertshooter has an MVIC value of 120 N or less?b. After repeated shooting sessions, what is the probabilitythat an expert shooter has an MVIC value of 120 N orless?c. What MVIC value will be exceeded by 75% of the expertshooters when at rest?d. Repeat part c for expert shooters following repeatedshooting sessions.e. If you observe an expert shooter with an MVIC value of120 N or less, what can you infer about when - at restor after repeated shooting sessions - the measurementwas taken?

A researcher is interested in testing the relationship between smoking and BMI (kg/m2) in adults aged 30-45. In order to test this association, the researcher divides smoking into currently more than a pack a day, currently less than a pack a day, and never smokers. The following table represents the BMIs for each participant enrolled by their respective smoking category. Current Smoker (≥1pack/day) Current Smoker (<1 pack/day Never Smoked 26.7 29.4 22.1 29.4 28.6 30.4 24.3 27.4 21.3 28.4 23.2 26.4 21.6 20.1 19.7 27.4 20.6 19.8 26.8 19.7 21.6 36.4 19.6 22.3 31.5 21.6 24.3 27.4 21.5 *Continue as though all assumptions for ANOVA are met.

The paper "Accelerated Telomere Shortening in Response to Life Stress" (Proceedings of the National Academy of Sciences (2004): 17312-17315) described a study that examined whether stress accelerates aging at a cellular level. The accompanying data on a measure of perceived stress (x) and telomere length (y) were read from a scatterplot that appeared in the paper. Telomere length is a measure of cell longevity. 5.38 Perceived Telomere Perceived Telomere Stress Length Stress Length 5 1.25 20 1.22 1.32 20 1.30 1.5 20 1.32 7 1.35 21 1.24 10 1.3 21 1.26 11 1 21 1.30 12 1.18 22 1.18 13 1.1 22 1.22 14 1.08 22 1.24 14 1.3 23 1.18 15 0.92 24 1.12 15 1.22 24 1.50 15 1.24 25 0.94 17 1.12 26 0.84 17 1.32 27 1.02 17 1.4 27 1.12 18 1.12 28 1.22 18 1.46 29 1.30 19 0.84 33 0.94 a.

How heavy a load (pounds) is needed to pull apart pieces of Douglas fir 4 inches long and 1.5 inches square? Students doing a laboratory exercise sample 20 pieces of wood and find an average load capacity of 30,841 pounds. We are willing to regard the wood pieces prepared for the lab session as an SRS of all similar pieces of Douglas fir. Engineers also commonly assume the characteristics of materials vary normally. Suppose that the strength of pieces of wood like these follow a normal distribution with a population standard deviation of 3,000 pounds (As you can see all three necessary assumptions are met). a. Assuming that all evergreen wood has a known "load" capacity average of 30,000 pounds. Make a two-sided hypothesis (null and alternative statement) about Douglas Fir "load" capacity compared to the overall average. b.
