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
Answer:
Step-by-step explanation:
Y) = 3
*multiply both sides by 8 - cancels out 8 in denominator*
x + 4 = 24
*subtract 4 from both sides*
x = 20
E) = 1
*multiply both sides by 2 - cancels out 2 in denominator*
x - 5 = 2
*add 5 on both sides*
x = 7
N) = 2
* multiply both sides by 4 - cancels out 4 in denominator*
x + 2 = 8
*subtract 2 from both sides*
x = 6
