The population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual.

For a sample of n=70, find the probability of a sample mean being greater than 230 if =229 and =5.9.

For a sample of n=70, the probability of a sample mean being greater than 230 if =229 and =5.9 is

nothing

.

(Round to four decimal places asneeded.)

Would the given sample mean be consideredunusual?

The sample mean

would

would not

be considered unusual because it

lies

does not lie

within the range of a usualevent, namely within

1 standard deviation

2 standard deviations

3 standard deviations

of the mean of the sample means.
