Answer:
0.0039 is the probability that the sample mean hardness for a random sample of 12 pins is at least 51.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 50
Standard Deviation, σ = 1.3
Sample size, n = 12
We are given that the distribution of hardness of pins is a bell shaped distribution that is a normal distribution.
Formula:
 
Standard error due to sampling =

P(sample mean hardness for a random sample of 12 pins is at least 51)
 
 
Calculation the value from standard normal z table, we have,  
 
0.0039 is the probability that the sample mean hardness for a random sample of 12 pins is at least 51.
