A sample of 34 observations is selected from a normal population. The sample mean is 45, and the population standard deviation is 5. Conduct the following test of hypothesis using the 0.02 significance level. H0: μ = 46 H1: μ ≠ 46 Is this a one- or two-tailed test? multiple choice 1 One-tailed test Two-tailed test What is the decision rule? multiple choice 2 Reject H0 if −2.326 < z < 2.326 Reject H0 if z < −2.326 or z > 2.326 What is the value of the test statistic? (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.)

Group of answer choices A.reject the null hypothesis, church attendance and marital status are independent B.fail to reject the null hypothesis, church attendance and marital status are independent C.Reject the null hypothesis, church attendance and marital status are dependent D.fail to reject the null hypothesis, church attendance and marital status are dependent
pleaseee sir solve question 24
I just need help with C-E If its helpful for A) I got 21 degrees of freedom and B) I got [-1.721, 1.721]
The test statistic for testing HO: mu = 100 against Ha: mu != 100 wast 3.3, with p-value of 0.001. Which of these is the correct conclusion? Since the p-value is very small, we conclud that mu != 100 Since the p-vaue is very smal, we are unable to conlude that mu != 100 Since the p-value is very small, we must conclude the mu = 100 In order to interpret the results, we must first know the sample size. Since the p-value is very small, we are unable to conclude that mu = 100.
3. For a z-test we get a test statistic of z=2.05. If our alternative hypothesis is "??:?>13Ha:μ>13", what Excel command would we use to compute the P-value? If our alternative hypothesis is "??:?<13Ha:μ<13", what Excel command would se use to compute the P-value?
