Answer:
If the person selected had high blood pressure, the probability that he or she did not exercise is P=0.643.
Step-by-step explanation:
We have a group of people between agss of 65 and 70.
They are divided in two groups regarding their amount of exercise: "none", "moderate" and "high".
The response variable is blood pressure, that was categorized as "normal"or "high".
Then, we have the frequencies table as:
Amount of exercise None Moderate High
Blood pressure High 54 23 7
Blood pressure Normal 86 76 32
We have to calculate the probability that, given that the person had high blood pressure, he or she did not exercise.
If the person had high blood pressure, it can be of the any of the 3 groups of exercise amount. There are 54 people with high blood pressure that did not exercise, 23 that did moderate amount of exercise, and 7 that did a high amount.
Then, the probability can be calculated dividing the amount of people that had high blood pressure and did not exercise, by all the people that have high blood pressure (regarding the amount of exercise):
If the person selected had high blood pressure, the probability that he or she did not exercise is P=0.643.
There are 10 seats in ferris wheel of love.
One couple can fit in to one seat. That means 1 couple per seat.
Given, in each minute a seat passes by the entrance or exit stage. That means one couple can use the seat for one minute. That means 1 seat per minute.
The wheel starts functioning at 8 p.m for half an hour. In 1 hour there are 60 minutes. So half an hour means = 30 minutes.
So we have got 1 couple per seat and 1 seat per minute. If we multiply them we will get 1 couple per minute.
We have got in 1 minute there is 1 couple.
So in 30 minutes there are couples = 30 couples.
We have got the required answer here.
There are 30 couples who took a ride in the ferris wheel of love.
