Answer:
A. 110 pounds,
C. 281 pounds
Step-by-step explanation:
Problems of normally distributed samples can be 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.
A measure is said to be an outlier if it has a pvalue lesser than 0.05 or higher than 0.95.
In this problem, we have that:
A. 110 pounds,
has a pvalue of 0.0179. So a weight of 110 pounds is an outlier.
B. 157 pounds,
has a pvalue of 0.702.
So a weight of 157 is not an outlier.
C. 281 pounds
has a pvalue of 0.9988.
So a weight of 281 is an outlier.
