I would appreciate it if someone could explain to me how to answer example 13 question #2 of reading 7
And for the test, do we need to memorize table 23(k, its interval around the sample mean, and proportion) of reading 7?
Can you rewrite the question for those who don’t have the book?
Chebyshev’s inequality gives the _ minimum _ percentage of observations that lie within a given (symmetric) interval about the mean. In Part 1 you created an interval that contains at least 75% of the observations, so at least 75% of the observations, or 783 (= 1,044 × 0.75) are in that interval. Chebyshev’s inequality _ doesn’t give _ a maximum percentage in the interval, so that maximum is 1,044 (i.e., all of them).
The rest of the answer uses data that weren’t given in the question. Not really cricket.
