Homework Answers
Answer:
The results are statistically significant.
Explanation:
Retain the null hypothesis means do not reject the null hypothesis, and we do not reject the null hypothesis when p-value is greater than 0.05. When confidence interval contains zero, this means we do not reject the null hypothesis that two population means are equal.
The results are statistically significant means we reject the null hypothesis. So, this statement is not equivalent to other three statements.

In order to compare the means of two populations, independent random samples of 400 observations are selected from each population, with the results found in the table to the right. Complete parts a through e below. Sample 1 overbar x = 5,305 s1= 154 Sample 2 overbar x = 5,266 s2 = 199 a.

A random sample of 40 adults with no children under the age of 18 years results in a mean daily leisure time of 5.09 hours, with a standard deviation of 2.29 hours. A random sample of 40 adults with children under the age of 18 results in a mean daily leisure time of 4.31 hours, with a standard deviation of 1.65 hours. Construct and interpret a 95% confidence interval for the mean difference in leisure time between adults with no...

Using a two-tailed one-sample z-test from a sample of size n, a researcher rejects the null hypothesis as z = 2.0 is greater than the critical value 1.96 at α = .05. What does this mean? Choose ALL the correct options from the following. a. As α = .05, the probability that the null hypothesis is correct is less than 5% b. As α = .05, the probability that the alternative / research hypothesis is correct is more than 95%...

You recently concluded a paired t-test. Which of the following means that you found a 95% CI for µd of CI (-3.64, 1.23), and a p-value of .06.? A.) The p-value is used to determine that we should not reject the null, because it is greater than .05, which shows there would be no difference between the means. Also, because 0 falls within our CI, 0 is a plausible value for µd and so we cannot reject the null. B.)...
