Question

Suppose the net profit per day (in thousands of dollars) at L & W Boutique is Normally distributed with a mean of 150 and a standard deviation of 20. The z-scores have been calculated for each weekday and charted below. Which day had the most unusual profit and was it a good profit day or a bad profit day

Answer 1

Explanation:

The further the z-score is from 0, the more unusual the statistic is.

In this case, Friday has the most unusual profit, since it has a z-score of 3, which is further from 0 than the others.

Since the z-score is positive, that means the profit was unusually high, so it was a good profit day.

Answer 2

BRO EASY

To determine which day had the most unusual profit, we need to analyze the z-scores of each weekday. The z-score measures how many standard deviations a data point is away from the mean. A higher absolute z-score indicates a more unusual data point.

However, you have not provided the z-scores for each weekday, so it's not possible to determine which day had the most unusual profit. If you can provide the z-scores or any further information regarding the z-scores for each weekday, I would be happy to assist you in analyzing the data and determining whether it was a good or bad profit day.

Apologies for the confusion earlier. To determine which day had the most unusual profit, we need to compare the absolute values of the z-scores for each weekday. The z-score measures how many standard deviations a data point is away from the mean. A higher absolute z-score indicates a more unusual data point.

Since you mentioned that the z-scores have been calculated and charted, please provide the z-scores for each weekday so that I can assist you in identifying the day with the most unusual profit and whether it was a good or bad profit day.
