Transcribed Image Text:2) The data below is the heart rate, in beats per minute, from 18 individuals after
two minutes of exercise on a treadmill.
78 87 88 89 90 95 96 97 98 102 | 104 105 107 108| 112 120 132 142
а.
Explore this data by producing a graph. You may choose any graph that is
appropriate for this type of data and allows you to describe the shape. NEATLY! You may
also use a computer to make an appropriate graph. Staple the graph to the back. (You
may use technology to create the graph or draw neatly by hand).
b. Briefly describe the shape of the distribution. You must use statistical language in your
description.
c. The average heart rate for all adults is 72 beats per minute. Does this sample suggest
that two minutes of exercise on a treadmill significantly increases the average heart
rate? Perform a hypothesis test to answer this question.
State appropriate hypotheses in symbols.
Null:
Alternate:
Find the Critical Value(s):
Find the Test Statistic:
Find the p-value:
Initial Conclusion:
Justification for initial conclusion using the critical value method:
Justification for initial conclusion using the p-value method:
State your conclusion clearly in complete sentences that reflect the context of this
scenario.
d. Your friend is a manager of a local gym. He is interested in including the results of this
study in an upcoming newsletter but seeks your advice first. Comment on any concerns
you may have about drawing conclusions from this study. (Note: You SHOULD have
