Question
Health researchers measure how often people exercise and how often the same people come down with the flu. The researchers find a negative correlation between the amount of weekly exercise and the number of flu symptoms in an individual. Based on this information, which of the following can we assume are TRUE? a People who exercise more tend to have the flu less often. b People who have the flu more often tend to exercise less. c Exercising causes people to be more healthy and less susceptible to the flu. d People who get sick do not have time to exercise. e Since exercise reduces the flu, this is really positive correlation because the result is good. f Since the flu is a bad thing, this makes it a negative correlation.Explanation / Answer
In this scenario as we talk about the health exercises and their effects on flue has got negative correlation, so we can straightway draw a conclusion saying that when one parameter is high the other one is low. Between the two variable the correlation is negative would impact one in a better place when the other parameter is down. In the same way if the people are exercising then they will fall sick less. Also those who are sock are unable to exercise.
The amount of weekly exercise is better for health as it can keep the flu at bay, but the persons those who are not doing are prone to be attacked by the flu.
Option a we can assume that the individual doing weekly exercise is falling sick less, in case if he stops in between, it does not guarantee that more exercise will protect them from flu. Let’s assume they have done more exercise in a day and consecutive days are blank, then they might catch the flu.
b. option talks about the opposite, though it may not be true, the healthy person can also be hit by the flue does not mean they exercise less.
C. talks about the health measure where if we are consistent with exercise we will be less susceptible to flu. This option seems like more prominent.
d. people who are sick do not have time is totally assumed and false, they might do exercise also they might fall sick, this option is incorrect.
e. exercise reduces the flu at the same time if flu is there people are unable to exercise, so the correlation is negative. This option also cannot be considered.
f. Since flu has a bad things it could also be get bettered and cured. So this option also seems to be wrong.
