Assume that a sample is used to estimate a population mean
μ
. find the margin of error m. e. that corresponds to a sample of size 21 with a mean of 62.9 and a standard deviation of 12.7 at a confidence level of 98%.

report me accurate to one decimal place because the sample statistics are presented with this accuracy.
m. e. =

step-by-step explanation:

this is not a question

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
