Pulse Rates of Identical Twins A researcher wanted to compare the pulse rates of identical twins to see whether there was any difference. Ten sets of twins were randomly selected. The rates are given in the table as number of beats per minute. At a=.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 ua be the average of twin A and ud= ua-ub . Twin A 83, 86, 93, 93, 91, 88, 85, 87, 90, 78 Twin B 93, 84, 78, 86, 83, 83, 93, 95, 79, 86 1. State the hypotheses and identify the claim H0: H1: Is this test one tailed or two tailed? 2. Compute the test value= t= 3. Find the interval for the P-value p value:

1. State the hypotheses and identify the claim
H0:
H1:
Is this test one tailed or two tailed?
2. Compute the test value=
t=
3. Find the interval for the P-value
p value:
4. Do not reject or Reject the null hypothesis
5. Is there enough evidence to support the claim
Please answer all parts of each question 1-5 and be sure the degree of freedom calculation is correct before calculating 2 and 3. Thanks in advance for the help.
