Question

the mean number of words per minute (wpm) read by sixth graders is 89 with a standard deviation of 16 wpm. if 66 sixth graders are randomly selected, what is the probability that the sample mean would differ from the population mean by more than 5.09 wpm? round your answer to four decimal places.

Answer 1

High

Explanation:

The probability is high because those 66 students could have 10 really fast readers that change that wpm. Or they could have 15 slow readers that could change the wpm and make it go down.

There are many possibilities.
