Part 1 of 4 (a) State the appropriate null and alternate hypotheses. Ho : H : This hypothesis test is a left-tailed V test. Part 2 of 4 (b) Compute the P-value. Round the answer to at least four decimal places. P-value= Part 3 of 4 (c) Determine whether to reject Ho. At the a = 0.10 level, reject the null hypothesis Ho- At the a=0.05 level, do not reject V the null hypothesis Ho- Submit Assignment
