Does the sample evidence suggest that the treatment is Individual 1 2 3 4 5 effective in decreasing the value of the response variable? Use the Before, X; 38 34 53 50 36 a = 0.05 level of significance. Complete parts (a) through (d). After, yi 37 31 51 47 32 (a) What type of test should be used? Choose the correct answer below. O A. A hypothesis test regarding the difference of two means using Welch's approximate t. O B. A hypothesis test regarding the difference of two means using a matched-pairs design. O C. A hypothesis test regarding two population standard deviations. O D. A hypothesis test regarding the difference between two population proportions from independent samples.(b) Determine the null and alternative hypotheses. Let Hy = Hx - Hy. Choose the correct answer below. O A. Ho: Hd = 0; H1: Hd 0 O C. Ho: Ha = 0; H1 : Hd #0 OD. Ho: Ha # 0; H1: Ha >0 (c) Use technology to calculate the P-value. (Round to three decimal places as needed.) (d) Draw a conclusion based on the hypothesis test. Choose the correct answer below. O A. There is not sufficient evidence to reject the null hypothesis because the P-value > a O B. There is not sufficient evidence to reject the null hypothesis because the P-value a.
