Answer:
0.964 is the probability that their mean shoulder breadth is less than 18.5 inch.
Step-by-step explanation:
Given:
Mean, μ = 18.2 inch
Standard Deviation, σ = 1.0 inch
n = 36
We are given that the distribution of shoulder breadths is a bell shaped distribution that is a normal distribution.
Formula:
a) P( mean shoulder breadth is less than 18.5 inch)
P(x < 18.5)
Calculation the value from standard normal z table, we have,
Thus, 0.964 is the probability that their mean shoulder breadth is less than 18.5 inch.
Yes, the result suggest that money can be saved by making smaller manholes with a diameter of 18.5 inch since 96.4% of the man holes have their mean shoulder breadth less than 18.5 inch.
