Step-by-step explanation:
Using it's concept, it is found that there is a 0.2979 = 29.79% probability that they are in chorus, given that they do not play a sport.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, 125 - 78 = 47 members of the band do not play a sport, of which 42 - 28 = 14 are in the chorus, hence the probability is given by:
p = 14/47 = 0.2979.

Behold the quotient of F and the product of r,s, and T: <em>F / (r·s·T)</em>
The weight loss in these three methods does not differ because the average weight loss is very similar in all 3.
<h3>How to calculate the average weight loss?</h3>
To calculate the average weight loss in these three situations, we must add all the values and divide the result by the number of values, for example:
- 7 + 7 + 5 + 4 + 6 = 29
- 7 + 8 + 8 + 9 + 5 = 37
- 7 + 9 + 7 + 8 + 8 = 39
- 39 ÷ 5 = 7.8
- 37 ÷ 5 = 7.4
- 29 ÷ 5 = 5.8
According to the above, it can be inferred that the hypothesis that the difference between one program and another is not significant enough to consider one plan more or less effective than another, because radically differences are not shown in each case.
