Using proportions, it is found that Juan spends 15 minutes on each 5-point problem.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and is solved using a rule of three.
In this problem, the amount of time is proportional to the amount of points the problem is worth. Hence, for a 5-point problem, in a 75-minute time, the time is given by:
t = 75/5 = 15 minutes.

D = k/c
2 = k/17
k = 2 x 17 = 34
Required equation is d = 34 / c
Answer:
0.0039 = 0.39% probability that a randomly selectedhuman resource manager received over $100,000 in 2007.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 76503, standard deviation of 8850.
This means that
a)What is the probability that a randomly selected human resource manager received over $100,000 in 2007?
This is 1 subtracted by the pvalue of Z when X = 100000. So
has a pvalue of 0.9961
1 - 0.9961 = 0.0039
0.0039 = 0.39% probability that a randomly selectedhuman resource manager received over $100,000 in 2007.
