Pulse Rates of Identical Twins A researcher wanted to compare the pulse rates of identical twins to see whether there was any difference. Eight sets of twins were selected. The rates are given in the table as number of beats per minute. At =α0.05 , is there a significant difference in the average pulse rates of twins? Use the P -value method. Assume the variables are normally distributed. Let μA be the average of twin A and =μD−μAμB . Find the 95% confidence interval for the difference of the two. Round your answer to one decimal place.   Question table Twin A 84 93 87 93 83 92 88 90 Twin B 83 84 79 86 80 89 86 93     Send data to Excel
