Suppose the time it takes for a purchasing agent to complete an online ordering process is normally distributed with a mean of 8 minutes and a standard deviation of 2 minutes. suppose a random sample of 25 ordering processes is selected. what is the standard deviation of the sampling distribution of mean times? (round to one decimal place.)

 0.4

Step-by-step explanation:

We know that the standard deviation of the sampling distribution of mean is given by:-

Given : Standard deviation :

Sample size : n= 25

Then, the standard deviation of the sampling distribution of mean times will be :-

Hence, the standard deviation of the sampling distribution of mean times=0.4
