You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test. H0:H120Ha:H12>0 The following results are for two independent samples taken from two populations: (a) Determine the degrees of freedom for the t-distribution. (Use Sample 1-Sample 2. Round your answer down to the nearest integer) (b) Compute the test statistic. (Round your answer to three decimal places.) (c) Determine the p-value. (Round your answer to four decimal places.) (d) Test the above hypotheses, Let a=0.05. Do not reject H0. There is insufficient evidence to conclude that 12>0. Reject H0. There is insufficient evidence to conclude that 12>0. Do not reject H0. There is sufficient evidence to conclude that 12>0. Reject H0. There is sufficlent evidence to conclude that 120
