Veterinary services among the Springfeild community would like to create an awareness concerning testing cats for kidney diseases following an article that describes cat's illness testing scenerio as follows : among cats , 2% have kidney diseas. Of test done , 82% can detect the disease when its there, 9.6% of the teat detect the disease when its not there the cat has the disease be D and the cat does not have the disease br D' The test turns positive be P and the test is negative be P' using bayes theorem find probability that cat will have the kidney disease given that the test turns out posi

In statistical testing, based on this given below, we could use parametric (ANOVA) or non parametric (Kruskal-Wallis) for testing the hypothesis. Using normality testing -- analytically and graphically, decide wether we use an anova (normally distributed) or kruskal-wallis test (not normally distributed).
Z-Test Z-Test Use the calculator displays to the right to make a decision to reject or fail to reject the null hypothesis at a significance level of α = 0.05. Inpt: Data Statsu #70 Ho:70 o:3.75 x:68.75 In:40 H:Ho Ho Ho Calculate Draw Choose the correct answer below. O A. Since the P-value is greater than x, fail to reject the null hypothesis. OB. Since the P-value is greater than x, reject the null hypothesis. OC. Since the P-value is less than x, reject the null hypothesis. O D. Since the P-value is less than x, fail to reject the null hypothesis. z=2.10818511 p=0.03501498 x = 68.75 n=40

The test statistic, t, The P-value is State the conclusion for the test. A. Fail to reject the null hypothesis. There is sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda. B. Reject the null hypothesis. There is not sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda. C. Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda. D. Reject the null hypothesis.
