Refer to Exercise 7.9. Assume now that the amount of fill dispensed by the bottling machine is normally distributed with \(\sigma=2\) ounces.
If \(\mathrm{n}=9\) bottles are randomly selected from the output of the machine, what is
\(\mathrm{P}(|\bar{Y}-\mu| \leq .3)\)? Compare this with the answer obtained in Example 7.2.
Find \(\mathrm{P}(|\bar{Y}-\mu| \leq .3)\) when \(\bar{Y}\) is to be computed using samples of sizes\(n=25, n=36, n=49, \text { and } n=64\)
What pattern do you observe among the values for \(\mathrm{P}(|\bar{Y}-\mu| \leq .3)\) that you observed for the various values of n?How do the respective probabilities obtained in this problem (where \(\sigma=2\)) compare to those obtained in Exercise 7.9 (where \(\sigma=1\))?Equation Transcription:
