Answer:
b) Both Veronica and Ron are a Big Deal.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation
, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Big deal:
Beat 97.5% of the other scores, which means that Z must have a pvalue of at least 0.975.
Ron
Scored 111, so
has a pvalue of 0.9927, so Ron is a big deal
Veronica
Scored 117, so
has a pvalue of 1, so Veronica is a big deal
So the correct answer is:
b) Both Veronica and Ron are a Big Deal.
