What are the most common reasons you would select a non-parametric test over the parametric alternative? Discuss the issue of statistical power in non-parametric tests (as compared to their parametric counterparts). Which type tends to be more powerful? Why? For each of the following parametric tests, identify the appropriate non-parametric counterpart: Dependent t test Independent samples t test Repeated measures ANOVA (one-variable) One-way ANOVA (independent) Pearson Correlation
Which samples show unequal variances? Use α = .05 in all tests. Show the critical values and degrees of freedom clearly and illustrate the decision rule.
Perform an appropriate hypothesis test, showing all critical steps. Do you support Bob's claim that citizens in his area spend more than $75 per year? Explain why or why not.
A sample of 65 business people was randomly selected and given a leadership test. Construct a 95 percent confidence interval for the mean score on this test, using the estimated standard error of the mean.
Assume if random samples of size n = 9 are selected can we say anything about the distribution of sample means.
Diastolic blood pressure (DBP) values were measured for 150 patients using two medical devices. The mean DBP values using the two devices are 120 and 122 respectively. Also the standard deviation of the difference of the measurements is 0.634. Te..
In an experiment, subjects are required to generate a "yes" or "no" decision. The probability of 'Yes' being correct is 50%. The observed probability of yes decisions is 70%.
When do you use a one-tailed test? How do you find the critical values for one-and two tailed tests? When do you reject the null hypothesis? Under what circumstances is the null accepted?
The population standard deviation is 100 hours. A random sample of 64 bulbs indicates the mean is 350 hours. At the .05 is there evidence that the mean life is different than 375 hours?
The booster club has gotten several businesses and car dealers to donate gasoline and cars for the college students to use to make a maximum of 575 personal contacts daily during the fund-raising drive. The college student will donate a total of 2..
The college theater department recently staged a production of a modern musical. A researcher recorded the gender of each student entering the theater and found a total of 385 females and 215 males.
To test the null hypothesis that the mean waist size for males under 40 years equals 34 inches versus the hypothesis that the mean differs from 34, the following data were collected: 33, 33, 30, 34, 34, 40, 35, 35, 32, 38, 34, 32, 35, 32, 32, 34, 36,..
Use this information to construct a probability table, and then calculate each of the following probabilities: P(foreign car)
