So, basically you have to get a data set, which you can almost freely choose the subject of. Then, you must get a visual representation, like a bar graph, with all of the data that you use. Make sure you label!! Lastly, all you have to do is answer all of the questions in part 3. Those include numbers 1, 2, 4, and 5. for number 3, you are able to choose between letters a and b, depending on either you or your subject. Then you just turn it in. Sorry if it was a vague description, but it's a pretty straightforward project. Hope it helped a little bit!!

At a competition with 5 runners

ankoles [38]

Answer:

B: Permutation; Number of ways = 60

Step-by-step explanation:

First we have to decide if this is a problem of permutation or combination. The rule is:

If the order matters, permutations will be used
If order does not matter, combinations will be used

In this problem, they order of awarding the medals matters, so this is a permutation problem.

We have to award 3 medals among 5 runners. So this can be done in 5P3 ways:

$nPr=\frac{n!}{(n-r)!}\\ \\ so\\ \\ 5P3=\frac{5!}{(5-3)!}=60$

Therefore, there are 60 ways to award the medal. Therefore, the correct answer is B.

Construct a 95% confidence interval for the population mean, µ. Assume the population has a normal distribution. A sample of 25

bixtya [17]

Answer:C. (77.29, 85.71)

Step-by-step explanation:

We want to determine a 95% confidence interval for the mean test score of randomly selected students.

Number of sample, n = 25

Mean, u = 81.5

Standard deviation, s = 10.2

For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.

We will apply the formula

Confidence interval

= mean +/- z ×standard deviation/√n

It becomes

81.5 +/- 1.96 × 10.2/√25

= 81.5 +/- 1.96 × 2.04

= 81.5 +/- 3.9984

The lower end of the confidence interval is 81.5 - 3.9984 =77.5016

The upper end of the confidence interval is 81.5 + 3.9984 =85.4984

Therefore, the correct option is

C. (77.29, 85.71)
