A physical therapist wanted to know whether the mean step pulse of men was less than the mean step pulse of women. She randomly selected 54 men and 70 women to participate in the study. Each subject was required to step up and down a 6-inch platform. The pulse of each subject was then recorded. The following results were obtained. Two sample T for Men vs Women N Mean StDev SE Mean Men Women 98% CI for mu Men - mu Women (- 12.20, - 1.00) T-Test mu Men = mu Women (vs H2 O C.

6. A kinesiologist wanted to examine the effects of temperature and humidity on exercise performance. Each participant was asked to walk on a treadmill at a normal pace for 60 minutes, and the kinesiologist recorded the distance walked (miles). She assigned participants to one of 4 conditions that varied in temperature (normal or high) and humidity (normal or high). Mean distance walked by the four groups are shown in the table below. Assume a = .05 and Tukey HSD = 0.39. Normal temperature High temperature Normal humidity M = 3.00 M = 2.80 High humidity M = 2.80 M = 2.00 Complete the following conclusion: The factorial ANOVA revealed significant main effects of temperature [F (1, 24) = 25.00, p<.05] and humidity [F (1, 24) = 19.65, p<.05] and a significant Temperature x Humidity interaction [F (1, 24) = 9.25, p < .05].
23. To test whether arousal or stress levels increase as the difficulty of a task increases, 24 participants (n = 8; N= 24) were randomly assigned to complete an easy, typical, or difficult task. Their galvanic skin response (GSR) was recorded. A GSR measures the electrical signals of the skin in units called microSiemens (µS), with higher signals indicating greater arousal or stress. The data for each task are given in the table. easy typical difficult 2.6 5.6 9.0 3.9 4.5 5.6 3.4 3.7 3.5 1.2 2.0 7.8 2.1 3.3 6.4 1.2 4.6 7.5 1.8 3.1 4.4 2.2 2.0 3.8 1. complete the F table and make a decision to retain or reject the null hypothesis 2. compute Turkeys HSD post hoc test and interpret the results.

Q2. Answer the following two questions under the assumption of normal populations with equal vari- ances. (a) The following are the numbers of sales which a random sample of nine salesmen of industrial chemicals in California and a random sample of six salesmen of industrial chemicals in Oregon made over a fixed period of time: (California) x; : 40, 46, 61, 38, 55, 63, 36, 60, 51 (Oregon) y; : 33, 62, 44, 54, 23, 42 Using s 5% level of significance, test whether or not California salesmen are more efficient in general. Write down the null and alternative hypothesis first. (b) Suppose that we wish to investigate whether males and females earn comparable wages in a cer- tain industry. Sample data show that 14 randomly surveyed males earn on the average $213.5 per week with a standard deviation of $16.5, while 18 randomly surveyed females earn on the average $194.1 per week with a standard deviation of $18.0. Let µi denote the average wage of males and 42 the average of females. Using a…
1.18 Cats on YouTube. Suppose you want to estimate the percentage of videos on YouTube that are cat videos. It is impossible for you to watch all videos on YouTube so you use a random video picker to select 1000 videos for you. You find that 2% of these videos are cat videos. Determine which of the following is an observation, a variable, a sample statistic (value calculated based on the observed sample), or a population parameter
Bighorn sheep are beautiful wild animals found throughout the western United States. Let x be the age of a bighorn sheep (in years), and let y be the mortality rate (percent that die) for this age group. For example, x = 1, y = 14 means that 14% of the bighorn sheep between 1 and 2 years old died.
