Suppose that a sample of size 100 is to be drawn from a population with standard deviation 10.
(a) what is the probability that the sample mean will be within 1 of the value of μ? (round the answer to four decimal places.)
p =
(b) for this example (n = 100, σ = 10), complete each of the following statements by computing the appropriate value. (round the answers to the nearest whole number.)
(1) approximately 95% of the time, x will be of μ.
(2) approximately 0.3% of the time, x will be farther from μ.
then,
a random sample is selected from a population with mean μ = 100 and standard deviation σ = 10. for which of the sample sizes would it be reasonable to think that the xsampling distribution is approximately normal in shape? (select all that apply.)
n = 12
n = 16
n = 40
n = 65
n = 130
n = 520

Monthly water bills for a city have a mean of $108.43 and a standard deviation of $32.09. find the probability that a randomly selected bill will have an amount greater than $155, which the city believes might indicate that someone is wasting water. would a bill that size be considered unusual?
