5. A researcher was interested in
comparing the resting pulse rate of people who exercise regularly
and people who do not exercise regularly. Random samples of
16 people aged 30-40 who do not exercise regularly and 12 people
aged 30-40 who do exercise regularly were selected and the resting
pulse rate of each person was measured.

At a 10% level of significance, is there sufficient evidence to
conclude that the mean resting pulse rate of people who do exercise
regularly is less than the mean resting pulse rate of people who do
not exercise regularly?
Answer parts (a) through (i).
5(a). Determine the
Hypotheses: State the null and alternative
hypotheses in words.
5(c). Collect the
Data. Enter values as decimals or whole
numbers. Round decimals to 2 decimal places.

s1 =
n1 =
x¯2 =
s2 =
n2 =
𝛼 =
df =
5(d). Assess the
Evidence:
(1) Calculate the standard
error SE . Round to 3
decimal places.
(2) Calculate the test statistic T.S. Round
to 2 decimal places.
Attach your calculations, otherwise no credit.
5(e) Check your calculations. Enter value
of the standard error, SE
5(f). Check your calculations. Enter
value of the test statistic, T.S.
5(g). Use the test statistic to find
the P-value. Round your answer to 3 decimal
places.
5(i). Interpret your decision in the
context of the problem.
