DESCRIPTIVE STATISTICS Comparing sample means Sample Word length (number of letters) Sample mean 1 7, 8, 7, 9, 6, 8, 3, 3 2 7, 7, 4, 9, 8, 6, 4, 6 0 3 5, 9, 8, 7, 4, 6, 9, 5 0 (b) Use the table to calculate the range of the sample means. Range of sample means: (c) The students are going to use the sample means to estimate the mean word length in the book. Select all the true statements below. A single sample mean will tend to be a worse estimate than the mean of the sample means. The mean of the sample means will tend to be a worse estimate than a single sample mean. The closer the range of the sample means is to 0, the less confident they can be in their estimate. The farther the range of the sample means is from 0, the less confident they can be in their estimate.

Question 1.1 Read the following and answer questions 1-5 about this actual study. Leisure-time physical activity (PA) patterns of adolescent boys and girls were studied. Data were collected from 1000 children in grades 9 through 12 using a self-report questionnaire administered in physical education classes. Depending on age and gender, 10% to 25% of youth report being completely sedentary. Contrary to the findings of most national-scope studies, there was little difference in the extent of participation in PA for boys and girls. They exercised less than 3 days a week for 30 minutes or more per occasion, far short of the national health goal of 75%. Findings also reveal that participation in leisure-time PA declines substantially with age (F=3.67, p=0.01). What types of statistical errors might have been made based on the conclusions drawn? With respect to age, a type II error could have been made. With respect to gender, no errors could have been made. With respect to gender, a type I error could have been made. Attempt #1: 0/1 Score: 0/1 Question 1.2 A progressive functional fitness strength training program using dumbbells and ankle weights was developed for the trained group, and 50 people were not trained. Five upper-body and five lower-body strength exercises were performed in a group setting 3 times per week for 30 minutes. Resistance of the dumbbells and ankle weights was progressed over an 8-week training period. Strength measurements were taken both pre and post-training. The two groups did not significantly differ in strength values at the pre-test (t=0.76, p=0.34). At the end of the training period, the trained group showed a significant increase in strength compared to the untrained group (t=3.003). We conclude that this functional fitness strength training program is a feasible and cost-effective program to conduct in a group setting. What type of statistical error might the researchers have made, if any, regarding the post-test? The results were significant, so no error could have been made. A type II error because of the age of the population. A type I error because they rejected the null hypothesis. A type II error because they accepted the null hypothesis. Attempt #1: 0/1 Score: 0/1

RC Circuit with Steady-State AC Source For the circuit of Fig. 5.1, assume V(t) is a 2V peak-to-peak (2V p-p = 1V = 1V peak) sinusoidal signal. Calculate the peak-to-peak values of VA and Vg for the three frequencies: 200 Hz, 1 kHz, and 5 kHz. For each frequency, determine the gain magnitude Vl/Val (the amplitude of V divided by the amplitude of V) and the phase angle between input (VA) and output (Vg) voltages (also called phase shift between VA and Vg or phase angle difference between VA and V), and complete the table below. Prelab Calculations: Fig. 5.1 Frequency VA VB V Vgain mag. Phase: V relative to V 200 Hz 1 kHz 5 kHz R = 1kÎ© Vs(c) C = 0.224F Fig. 5.1
