Use the Table Below to Answer the Following Questions) -From the Table Above, Determine the Cumulative Probability for Z

Use the table below to answer the following questions) .
The historical data of Velvetta Inc., a healthcare products manufacturer, have shown that in a production process for filling bottles of shampoo, variance in the volume is constant; however, clogs in the filling machine often affect the mean volume. The historical standard deviation is 5 milliliters. In filling 250-milliliter bottles, a sample of 20 found a mean volume of 242 milliliters. $$\begin{array}{l}\begin{array} { | l | l | } \hline\text { Velvetta Inc. Shampon }\\ \text { Productim } & \\\hline \text { Alpha Vulue } & 0.05 \\\hline \text { Standard Deviation } & 5 \\\hline \text { Sample Size } & 20 \\\hline \text { Sample Mean } & 242 \\\hline\end{array}\end{array}$$
