Answer 2

I don't know if you want the sample or population standard deviation.
If your posted data is all there is (not a sample), then I think I'd go with the population standard dev although I do not know the source of the data set.

Answer 3

total number is 8
mean :51.25
sd:10.08

Answer 4

Now, do this: "Round to the nearest tenth." Post what you get.

Answer 5

mean:51.0
sd:10.0

Answer 6

Select one:
a. mean = 51.3;
standard deviation = 9.4
b. mean = 51.3;
standard deviation = 88.9
c. mean = 47.5;
standard deviation = 9.4
d. mean = 47.5;
standard deviation = 88.9

Answer 7

this the chose.

Answer 8

No.

mean :51.25 --> 51.2 5

Question: I the 5 in the hundredths place greater than or = to 5?
If so, round the 2 in the tenths place to 3 to get 51.3 to the nearest tenth.

Answer 9

i don't get ?

Answer 10

It appears from the options that you are to go with the population standard deviation.

Is 3 greater than or equal to 5?
