Formula used:
Calculation:
Probability of 5% = 0.05 and 95% =0.95
Z-score for corresponding to 0.05 is -2.575
Z-score for corresponding to 0.95 is 1.645
For z = -2.575
For z= 1.645
Therefore the soldiers who have a head circumference of less than 19.965 inches or more than 24.6095 inches get a custom-made helmet.
