Send data to Excel
Assume the population standard deviation is o = 89.
Part 1 of 3
Explain why it is necessary to check whether the population is approximately normal before constructing a confidence
interval.
It is necessary to check whether the population is approximately normal because
the sample size is less than or equal to 30
Part 2 of 3
Following is a dotplot of these data. Is it reasonable to assume that the population is approximately normal?
