Use a 0.05 significance level to test the claim that the mean resting pulse rate of people who do not exercise regularly is larger than the mean resting pulse rate of people who exercise regularly. Use the traditional method of hypothesis testing. a. Write the null and alternative hypotheses to test this claim. b. What is the value of the test statistic? Show your work. c. What is the associated P-value? c. State your conclusion and explain in context using ΅ = 0.05.
A researcher was interested in comparing the resting pulse rates of people who exercise regularly and of those who do not exercise regularly. Independent simple random samples of 16 people who do not exercise regularly and 12 people who exercise regularly were
selected, and the resting pulse rates (in beats per minute) were recorded. The summary statistics are as follows.
Do not exercise regularly
x1= 73.0 beats/min
s1 = 10.9 beats/min
n1 = 16
Exercise regularly
x2= 68.4 beats/min
s2 = 8.2 beats/min
n2 = 12
Use a 0.05 significance level to test the claim that the mean resting pulse rate of people who do not exercise regularly is larger than the mean resting pulse rate of people who exercise regularly. Use the traditional method of hypothesis testing.
a. Write the null and alternative hypotheses to test this claim.
b. What is the value of the test statistic? Show your work.
c. What is the associated P-value?
c. State your conclusion and explain in context using ΅ = 0.05.
