Question

30.
In a small business firm, two typists are employed-typist A and typist B. Typist A
types out, on an average, 30 pages per day with a standard deviation of o. Typist
B, on an average types out 45 pages with a standard deviation of 10. Which typist
shows greater consistency in his output?​

Answer 1

Typist 1: 30 pages with standard deviation of 6

Typist 2: 45 pages with standard deviation of 10

Typist 1: 6 / 30 = 1 / 5 = 20% error

Typist 2: 10 / 45 = 2 / 9 =~ 22.22% error

Since Typist 1 has less error, he is more consistent.

Hope this helps :)
