I NEED HELP WITH THESE THREE QUESTIONS QUICKLY

Ladies' shoes: A random sample of 100 pairs of ladies' shoes had a mean size of 7.6. Assume the population standard deviation is o = 1.6. that the mean size of ladies' shoes differs from 8? Use the a = 0.01 level of significance. Ho : M = 8 H: M # 8 Part: 0 / 3 Part 1 of 3 (a) Find the P-value. Round your answer to at least four decimal places. The P-value is 0.347 X Part: 1 / 3 Part 2 of 3 (b) What is the decision? O Reject H X Do not reject Ho ContinuePart 2 of 3 (b) What is the decision? O Reject H X Do not reject Ho Part: 2 / 3 Part 3 of 3 (c) Interpret the result. We (Choose one) enough evidence at the 0.01 level of significance to conclude that the mean size of ladies' sho have do not have X
