5-14 points PODS 4 4 E.045 A sample of concrete specimens of a certain type is selected, and the compressive strength of each specimen is determined. The mean and standard deviation are calculated asx-600d and - 300, and the sample histogram is found to be well approximated by a normal curve. (a)Approximately what percentage of the sample observations are between 5700 and 63007 (Round the answer to the nearest whole number) (b) Approximately what percentage of sample observations are outside the interval from 5400 to 66007 (Round the answer to the nearest whole number) (c) What can be said about the approximate percentage of observations between 5400 and 5700? (Round the answer to the nearest whole number.) Approximately (d) why would you not use Chebyshev's Rule to answer the questions posed in parts (a)-(c)? O Chebyshev's Rule typically gives much larger values than are appropriate for a normal distribution O Chebyshev's Rule is the best way to solve this problem O Chebyshev's Rule is not used because the histogram is well approximated by a normal curve O Chebyshev's Rule does not apply to the normal distribution O Chebyshev's Rule does not apply to values in these ranges My Notes Ask Your Teache SA5/5 points I Previous Answers Po0SS 4.E 046
