This doesn’t make sense, please rephrase this.
The number of ways the skaters can finish the competition is 40,320 ways
The different ways 3 of the skaters finish first, second and third is 56 ways
Given the following
- Number of skaters featured = 8 skaters
If the skaters finish the competition, the number of different ways the skaters finish the competition is expressed as:
8! = 8*7*6*5*4*3*2
8! = 56*30*24
8! = 40,320.
The number of ways the skaters can finish the competition is 40,320 ways
If 3 of the skaters finish first, second and third, the number of ways this can be done is given as:
8C3 = 8!/(8-3)!3!
8C3 = 8!/5!3!
8C3 = 8*7*6*5!/5!3!
8C3 = 56 ways
Hence the different ways 3 of the skaters finish first, second and third is 56 ways

Answer:
<em>There is no evidence to warrant rejection of the claim that the mean is 18.7 months or no evidence to test the claim that convicted burglars spend an average of 18.7 months in jail.</em>
Explanation:
<em>From the question given, we recall the following,</em>
<em>The researcher takes a random sample of 11 such cases from the court files and finds that ẋ is:</em>
<em> When s = 7.8 months and 20.6 months</em>
<em> Let Test the claim that µ = 18.7 months, when the significance level is at 0.05
</em>
<em> significance level. </em>
<em>We apply the use the traditional method of testing hypotheses</em>
<em> H0: µ = 18.7 mo. H1: µ J 18.7 mo. </em>
<em>Test statistic: t = 0.81. Critical values: t = ±2.228. Fail to reject H0. </em>
<em>Therefore,</em>
<em>There is no evidence sufficient to warrant rejection of the claim that the mean is 18.7 months</em>
