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 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.
Normally distributed with a mean of 5.8-in and a standard deviation of 0.8-in.
This means that
1. What is the minimum head breadth that will fit the clientele?
The 4.1st percentile, that is, X when Z has a pvalue of 0.041, so X when Z = -1.74.
The minimum head breadth that will fit the clientele is of 4.41-in.
2. What is the maximum head breadth that will fit the clientele?
100 - 4.1 = 95.9th percentile, that is, X when Z has a pvalue of 0.959, so X when Z = 1.74.
The maximum head breadth that will fit the clientele is of 7.19-in.
