Test the claim that the proportion of men who own cats is smaller than the proportion of women who own cats at the .005 significance level. The null and alternative hypothesis would be: H0:pM≥pFH0:pM≥pF H1:pMμFH1:μM>μF H0:μM=μFH0:μM=μF H1:μM≠μFH1:μM≠μF H0:pM=pFH0:pM=pF H1:pM≠pFH1:pM≠pF H0:pM≤pFH0:pM≤pF H1:pM>pFH1:pM>pF The test is two-tailed right-tailed left-tailed Based on a sample of 80 men, 40% owned cats Based on a sample of 40 women, 70% owned cats Critical Value =     [three decimal accuracy]     Test Statistic =     [three decimal accuracy] Based on this we: Fail to reject the null hypothesis Reject the null hypothesis

In order to determine if the average bacteria content of southern flowing streams is less than the average bacteria content of northern flowing streams, independent random samples of 28 southern flowing streams and 35 northern flowing streams were taken. Given the testing statistics below, determine if the data provides sufficient evidence to conclude that the average bacteria content of southern flowing streams is less than the average bacteria content of northern flowing streams, at the 5% significance level. H0:μs≥μnHa:μs<μn t0=−0.108 t0.05=−1.999 Select the correct answer below:   No; the test statistic is less than the critical value.   Yes; the test statistic is greater than the critical value.   No; the test statistic is greater than the critical value.   Yes; the test statistic is less than the critical value.

Q4) Suppose that when data from an experiment was analyzed, the P-value for testing Ho: u = 100 versus Ha: µ < 100 was calculated as 0.047. At the 0.01 significance level, Họ would

A published report of a repeated-measures research study includes the following description of the statistical analysis: “The results show significant different among the treatment conditions, F(2, 26) = 4.87, p < .05.” A)How many treatment conditions were compared in the study? B)How many individuals participated in the study?
