The following data are from a simple random sample. 5 7 11 8 11 12 (a) What is the point estimate of the population mean? (b) What is the point estimate of the population standard deviation? (Round your answer to one decimal place.)
Added by Nuria H.
Step 1
We add up all the numbers and divide by the number of numbers. 5 + 7 + 11 + 8 + 11 + 12 = 54 There are 6 numbers, so we divide 54 by 6 to get 9. So, the point estimate of the population mean is 9. (b) The point estimate of the population standard deviation Show more…
