Ineed the answer asap the standard deviation of a population is known to be 7.8. if the sample size is 85, what is the standard error of the mean? a.0.22 b.0.85 c.1.047 d.6.008

0.85

Step-by-step explanation:

We are given that The standard deviation of a population is known to be 7.8.

So,

Population size N = 85

Formula of standard error of the mean =

Substitute the values in the formula:

So, standard error of the mean =

                                                     =

Thus the standard error of the mean is 0.85

Hence Option B is correct.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
