Question

These intervals are incorrect. Can someone help me find the right interval?

Assume that the differences are normally distributed. Complete parts (a) through (d) below. Observation 1 2 7 41.0 54.5 49.6 48.2 49.0 48.8 49.4 46.7 45.4 53.4 52.7 52.8 48.6 51.9 53.7 48.9 P-value 0.007 (Round to three decimal places as needed.) Choose the correct conclusion below. A. Reject the null hypothesis. There is sufficient evidence that ?,-0 at the ?:0.05 level of significance Do not reject the null hypothesis. There is sufficient evidence that ?,-0 at the ? 0.05 level of significance. O B. C. Reject the null hypothesis. There is insufficient evidence that ?,-0 at the ?:0.05 level of significance 0 D. Do not reject the null hypothesis. There is insufficient evidence that ?,-0 at the ? 0.05 level of significance. (d) Compute a 95% confidence interval about the population mean difference d The lower bound is-4.34 The upper bound is-0.91 Round to two decimal places as needed.)

Explanation / Answer

-0.70

Lower bound = -4.35

Upper Bound = -0.70
