Columbia manufactures bowling balls with a mean weight of 14.6 pounds and a standard deviation of 1.6 pounds. A bowling ball is too heavy to use and is discarded if it weighs over 16 pounds. Assume that the weights of bowling balls manufactured by Columbia are normally distributed. \begin{tabular}{|c|c|c|} \hline \multicolumn{3}{|c|}{ (In Ibs) } \\ \hline Mean & Standard Deviatior & Cutoff Weight \\ \hline 14.6 & 1.6 & 16 \\ \hline \end{tabular} Required: a) What is the probability that a randomly selected bowling ball is discarded due to being too heavy to use? 0.190786953 defects. A bowling ball is discarded for being too light if it weighs under what specific weight? 12.11236225 c) What is the probability that a randomly selected bowling ball will be discarded for being either too heavy or too light? =NORM.INV(0.06,A6,B6)
