Transcribed Image Text:Imagine that we take a sample from a population of interest.
For the following questions use the sample values to the right:
Use the sample standard deviation to estimate the population value.
Assume that this sample accurately reflects the mean and standard
deviation of the population so you can use the normal distribution and
Z scores for the problems below. (If you've read ahead in your book or
lab manual you know we should really use t scores, don't worry about this right now, use the Z scores)
Q15. Assuming that the population data is normally distributed, what is the value
that you expect 67% of the data in the population to be smaller than?
