Answer: 0.4302
Step-by-step explanation:
Given : Mean :
Standard deviation :
Sample size :
Also, these distances are normally distributed.
Then , the formula to calculate the z-score is given by :-
For x=32.5
For x=40.5
The p-value =
Hence, the required probability :-0.4302
500x3=1500
80x3=240
4x3=12
1500+240+12=1,752
