Agroup of statistics students conducted a random sample of 64 students at their college. their findings showed that the sampled students studied an average of 15 hours per week with a standard deviation of 5 hours. what is the value for the standard error of the means?

0.8333

Step-by-step explanation:

Given that a group of statistics students conducted a random sample of 64 students at their college.

Their findings showed that the sampled students studied an average of 15 hours per week with a standard deviation of 5 hours

i.e we have

sample size =

Standard deviation of sample s =

By central limit theorem we have sample mean will follow a normal distribution with mean = sample mean and std error = std deviation /square root of n.

Substitute the values to get

Standard error of means =

c

step-by-step explanation:

i think because what else can be a sample of every member

i hope this is what you were looking for.
