Question

4. Dougall compared the resting heart rate of average healthy citizens and soldiers
suffering from post-traumatic stress disorder (PTSD). The normal resting heart rate
for 25 healthy people averages 65 beats per minute (bpm) with a standard deviation
of 6 bpm. The average heart rate of 16 people suffering from PTSD was 82 bpm with
a standard deviation of 8 bpm. Use a = .05 for a two-tailed test. Does PTSD cause an
elevation in resting heart rate? Complete all 4 steps of hypothesis testing.

Many psychologists are concerned that the average level of anxiety in children has increased over the past 40 years. In the 1980s, the population average score on the Child Manifest Anxiety Scale (CMAS) was 15.1. In 2021, a random sample of 101 children was tested with CMAS. The mean for the sample was 16.1 with the standard deviation of 4. Is there enough evidence to claim that there has been a significant change in the average level of anxiety since the 1980s? Conduct the appropriate statistical test (two- tailed) with a = .05. Based on the information provided above, which statistical test seems most appropriate? independent samples t test z test dependent samples t test one sample t test

A researcher wanted to know whether losing one night sleep can affect problem solving. A sample of n = 25 college students was given a problem-solving task at noon on one day and again at noon on the following day. The students were not permitted any sleep between the two tests. For each student, the difference between the first and the second score was recorded: MD = 5 and standard deviation of the difference score was s = 10. Do the data indicate a significant change in problem solving ability? Use a two-tailed test with α = .01. a. The alternative hypothesis in words is b. The null hypothesis in symbols is c. The critical t-values are d. The t-statistic is e. Your decision is
Dr. Shoals predicts that people who walk a mile in moderately high heels will have less back pain than when they walk in very high heels. 27 participants walk in 4-inch heels and then 2.5-inch heels. He calculates the standard deviation of the difference scores and finds sD = 3.37. The mean back pain when walking in 4-inch heels is 6.75, and when walking in 2.5-inch heels, it is 3.25. What is the t statistic for this experiment
