In a random sample of 75 men, 22 men owned cats. The P-value of this sample is (to 4 decimals). Based on this we: Reject the null hypothesis We address the original claim with the conclusion. There is insufficient evidence to reject the proportion of men who own cats is 15% with 0.01 significance level. O The proportion of men who own cats is 15% with 0.01 significance level. O The proportion of men who own cats is not 15% with 0.01 significance level. O There is insufficient evidence that the proportion of men who own cats is significantly different than 15% with 0.01 significance level

In each part, we have given the value obtained for the test statistic, z, in a one-mean z-test.We have also specified whether the test is two tailed, left tailed, or right tailed. Determine the P-value in each case and decide whether, at the 5% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. a. z = -1.25; left-tailed testb. z = 2.36; right-tailed testc. z = 1.83; two-tailed test

Is there an association between grade level and whether the student makes their bed in the morning? To investigate, the principal at a large high school selects a random sample of 84 students and classifies them as being in ninth, tenth, eleventh, or twelfth grade, and whether they make their bed. He would like to determine if there is convincing evidence of an association. Let a = 0.05. What are the hypotheses for this test? O Ho: There is no association between grade level and whether the student makes their bed in the morning. Hạ: There is an association between grade level and whether the student makes their bed in the morning. O Ho: There is an association between grade level and whether the student makes their bed in the morning. Hạ: There is no association between grade level and whether the student makes their bed in the morning. O Ho: There is a difference in the distribution of grade level and whether the student makes their bed in the morning. Hạ: There is no difference in…
(...) Dairy cows - The USDA collects and distributes a wide variety of data about agriculture in the United States. One statistic reported each year is the number of milk cows (in thousands) in each state. A random sample of 10 states is selected, with the number of milk cows reported in both 2011 and 2015. 1. Which hypotheses should be used to conduct the test? diff=0 vs. H₁ : 0 vs. Ha diff 5.7 20.202 mean sd 2015 19 47 125 195 14 1279 14 408 2011 19 45 119 188 14 1265 18 366 329 323 98 94 246.1 251.8 379.881 385.58 Difference 0 2 6 7 0 14 -4 42 -6 -4 5.7 14.111 3.
