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. =

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.

a ≈ 172.05

step-by-step explanation:

the pictures.

the answer to this is:

factor 2x2+16x+24

2x2+16x+24

=2(x+2)(x+6)

answer:

2(x+2)(x+6)
