1. An advantage of the permutation test over the t test for a difference in means is thatA. it gives accurate P-values even when the distributions are not normal.B. it tests a more general hypothesis.C. Both choices are true.
2. Permutation tests cannot be used forA. tests when we believe the two populations differ under the null hypothesis.B. matched pairs designs where we believe only random differences occur.C. testing relationships where the null hypothesis says no relationship exists.
3. Which is more accurate?A. a t distribution confidence intervalB. a bootstrap BCa intervalC. a bootstrap percentile interval
If a claim is randomly selected, what is the probability the person was under 25 or male?
If you have a population that has a small sample, but does not meet all of the criteria for the nonparametric test how can you tell what test to use?
For the statement: The mean amount of Pepsi in cans is at least 12 oz. Express the null hypothesis and the alternative hypothesis in symbolic form.
The Appliance Center has six sales representatives at their North Jacksonville outlet. Listed below is the number of refrigerators sold by each last month.
A professor obtains SAT scores and freshman grade point averages (GPAs) for a group of n=15 college students. The SAT scores have a mean of M=580 with SS=22,400, and the GPAs have a mean of 3.10 with SS=1.26, and SP=84.
If the average importance were computed for each group, would you expect the sample means to be similar or different? What was the total sample size in this study?
B is independent of C or not? Focus on probabilities assigned in the subsets, 0.05 is repeated in C, but 0.10 is repeated in B, so P(A∩C)=?
Find P-Value with 0.05 significance level, and state the conclusion about the null hypotheses (reject or fail to reject) With H1: p is not equal to 3/4, the test statistic is z=0.35
How much error, on average, would you expect between the sample mean (M) and the population mean for: a sample of n=4 scores, a sample of n=16 scores, and a sample of n=25 scores.
Develop a 99% confidence interval for the population proportion.
Can we conclude that the mean time for a game is less than 3.50 hours? Use the .05 significance level.
Let p represent the population proportion of all numbers in the corporate file that have a first nonzero digit of 1. Test the claim that p is less than 0.301 by using What is the P-value of the test statistic?
