Question

Suppose a random sample of n = 118 measurements is selected from a population with mean μ = 26 and standard deviation σ = 3. Find the value of the standard error rounded to one decimal place.

Answer 1

Solution :

Given that ,

mean = = 26

standard deviation = = 3

n = 118

= = 26

= / n = 3/ 118 = 0.3

standard error = = 0.3
