According to the CDC website, 80% of people do not get the recommended amount of exercise. Kathy grew up in a very active family, however, and finds this statistic hard to believe. She wants to know if less than 80% of people in her community actually do not get enough exercise. To investigate, she selected an SRS of 200 adults in her community and found that 140 do not get the recommended amount of exercise. To determine if these data provide convincing evidence that less than 80% of the adults in her community do not get enough exercise, 100 SRSs were simulated to be selected. Each dot in the graph shows the number of adults that do not get enough exercise assuming that each person has an 80% chance of not getting enough exercise. ............/////..... 164 166 168 170 146 148 150 152 154 156 158 160 162 Simulated sample count of people that do not get enough exercise Based on the results of the simulation, is there convincing evidence that less than 80% of adults i Kathy's community do not get enough exercise? No, based on the simulation, none of the simulated samples show 140 or fewer people that do not get enough exercise. This means that there is no convincing evidence that less than 80% of adults in Kathy's community do not get enough exercise. Yes, the simulation is centered near 160, which is 80%, just like the CDC's claim. This provides convincing evidence that less than 80% of adults in Kathy's community do not get enough exercise. Yes, based on the simulation, none of the simulated samples show 140 or fewer people that do not get enough exercise. Because it would be very surprising to get a sample count of 140 or less when the population proportion is 80%, we would be skeptical that the CDC claim applies in Kathy's community. No, based on the simulation, about half of the simulated samples show 140 or fewer people that do not get enough exercise.

According to the CDC website, 80% of people do not get the recommended amount of exercise. Kathy grew up in a very active
family, however, and finds this statistic hard to believe. She wants to know if less than 80% of people in her community actually
do not get enough exercise. To investigate, she selected an SRS of 200 adults in her community and found that 140 do not get
the recommended amount of exercise.
To determine if these data provide convincing evidence that less than 80% of the adults in her community do not get enough
exercise, 100 SRSs were simulated to be selected. Each dot in the graph shows the number of adults that do not get enough
exercise assuming that each person has an 80% chance of not getting enough exercise.

Simulated sample count of people that do not get enough exercise
Based on the results of the simulation, is there
convincing evidence that less than 80% of adults in
Kathy's community do not get enough exercise?
O No, based on the simulation, none of the simulated
samples show 140 or fewer people that do not get
enough exercise. This means that there is no
convincing evidence that less than 80% of adults in
Kathy's community do not get enough exercise.
Yes, the simulation is centered near 160, which is
80%, just like the CDC's claim. This provides
convincing evidence that less than 80% of adults in
Kathy's community do not get enough exercise.
Yes, based on the simulation, none of the simulated
samples show 140 or fewer people that do not get
enough exercise. Because it would be very
surprising to get a sample count of 140 or less when
the population proportion is 80%, we would be
skeptical that the CDC claim applies in Kathy's
community.
No, based on the simulation, about half of the
simulated samples show 140 or fewer people that do
not get enough exercise. This means that there is not
convincing evidence that less than 80% of adults in
Kathy's community do not get enough exercise.
No, the simulation is centered near 160, which is
80%, just like the CDC's claim. This does not
provide convincing evidence that less than 80% of
adults in Kathy's community do not get enough
exercise.
