Answer:
0.3707
Step-by-step explanation:
Mean length = 30.05 inches
Standard deviation = 0.3 inches
We are supposed to find the probability that the average length of a steel sheet from a sample of 9 units is more than 29.95 inches long
Formula :
x= 29.95
Substitute the values :
Refer the z table for p value
p value = 0.3707
So, the probability that the average length of a steel sheet from a sample of 9 units is more than 29.95 inches long is 0.3707
