Have a nice day!
Um 4.2 maybe since -4.2 and 4.2 or on the opposite scale

-15
Step-by-step explanation:
Trust
Standard error of the mean is computed by:
Standard error = SD/ sqrt N
Where:
N is the sample size
SD is the standard deviation
To get the standard deviation, you need to get the sqrt of
the variance = sqrt 9 = 3
So plugging in our data:
Standard error = 3 / sqrt (16)
= 0.75
