Answer: The population would be the data of temperatures of all food served by the restaurant.
Step-by-step explanation:
In a statistical study, the term population refers to the largest group of all individuals related to the study or the objective of the study.
Here, the objective of the study= To check the temperatures of food just before serving.
Population = Data of temperatures of all dishes served by restaurant.
Hence, the population would be the data of temperatures of all dishes served by the restaurant.
First, convert the distance of a typical marathon to kilometers.
1 mi = 1.609 km
26.2 miles = 42.165 km
Divide this distance by Allan's average speed to get his average time.
42.165 km / 12 km/hr = 3.514 hours
Looking at the graph closely we can see that the heart rate increases from 0 to 6 min then became steady from 6 to 25 min then finally decreases from 25 to 30 min. Therefore the correct answer is:
“The heart rate increases for 6 minutes, remains constant for 19 minutes, and then gradually decreases for 5 minutes.”
In real life cardiac exercises, we can interpret that the period from 0 to 6 min is the period where the person is still warming up thus leading to an increase in heart rate. At 6 min, the person is fully warmed up hence reaching a stable heart rate. Then at 25 min, the person starts cooling down which means that the exercise is ending soon.
