Living Arrangements A recent study of 100 individuals found the following living arrangement for men and women. The results are shown. Check the data for a dependent relationship at =α0.01. Use the critical value method with tables. Spouse Relative Nonrelative Alone Men 57 10 26 7 Women 43 6 28 23 Step 1: State the hypotheses and identify the claim with the correct hypothesis. One/Two tailed? Step 2: Find the critical value. Step 3: Compute the test value. Step 4: Make the decision. Step 5: Summarize the results.
Consider the following data on price ($) and the overall score for six stereo headphones tested by a certain magazine. The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). Brand Price ($) Score 180 74 В 150 69 95 63 70 56 70 40 F 35 28 (a) The estimated regression equation for this data is ý = 25.870 + 0.291x, where x = price ($) and y = overall score. Does the t test indicate a significant relationship between price and the overall score? Use a = 0.05. State the null and alternative hypotheses.

weight is recorded in grams. Linda feeds her rats Formula A, Tuan feeds his rats Formula B, and Javier feeds his rats Formula C. At the end of a specified time period, each rat is weighed again, and the net gain in grams is recorded. Using a significance level of 0.05, test the hypothesis that the three formulas produce the same mean weight gain.H0: μ1 = μ2 = μ3Ha: At least two of the means differ from each other Forumla A Forumla B Forumla C 51 39.4 53.6 55.8 55.1 42.4 53.8 33.1 50.1 43.2 58.7 40.4 42.1 40.4 46.9 50.1 19 45.6 59.5 43.2 48.7 35.4 32.2 49.5 45.2 16.4 56.1 Run a one-factor ANOVA with α=0.05.

The summary statistics for a certain set of points are: n=25, s = 121.69, Σ (x-x)² =42.30, and b₁ = 24.99. Use the critical value method to test the null hypothesis Ho : B₁ = = 0 versus H₁ B₁ +0. Use the a= 0.05 level of significance. Part: 0 / 4 Part 1 of 4 Find the critical value(s). Round the answer to three decimal places. If there is more than one critical value, separate them with commas. Critical value(s): 0,0,... X +0 Ś
C Find the critical z value using a significance level of a = 0.07 if the alternative hypothesis Ho is u < 68.
Use the given information to find the p-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). With H 1: p≠0.377, the test statistic is z=3.06.
At an art store, the mean sale amount is $1250 per customer. The owner thinks that the mean sales amount increases during promotion. A random sample of 45 paintings purchased during a promotion was selected, the sample mean sales amount is x¯=1315. Assume σ=$155. How can I implement the hypothesis test to check if the mean sales amount increases during promotion, and let α=0.01. I want to solve by both P-value method and reject region method.
