In this example,μd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the measurement from the right arm minus the measurement from the left arm. what are the null and alternative hypotheses for the hypothesis test? a. h0: μd≠0h1: μd=0b. h0: μd≠0h1: μd> 0c. h0: μd=0h1: μd≠0d. upper h0: μd=0h1: μd< 0identify the test statistic. t=(round to two decimal places as needed.)identify the p-value. p-value=(round to three decimal places as needed.)what is the conclusion based on the hypothesis test?
