Question
One of the most popular products sold by a manufacturer of electrical fuses is the standard 30-ampere fuse used by electrical contractors in the construction industry. The company has tested a simple random sample of 16 fuses and found that the amperages at which they blew are as follow:
30.6
30.2
27.7
28.5
29.0
27.5
28.9
28.1
30.3
30.8
28.5
30.3
30.0
28.5
29.0
28.2
Given this information and assuming the data are from a normally distributed population; calculate the mean,
30.6
30.2
27.7
28.5
29.0
27.5
28.9
28.1
30.3
30.8
28.5
30.3
30.0
28.5
29.0
28.2
Explanation / Answer
We have asked to find the mean .
mean = sum of all the values / total number of values
Sum of all the number = 30.6+30.2+27.7+28.5+29.0+27.5+28.9+28.1+30.3+30.8+28.5+30.3+30+28.5+29+28.2 = 466.1
total number of values = 16
mean = 466.1/16 = 29.13125
Final answer :-
Mean = 29.13125
