QUESTION 19:

What are the expected number of yearly breakdowns for the power generator at Niagara Falls that has exhibited the following data over the past 20 years? \begin{tabular}{llllllll} & \multicolumn{1}{l}{} & \\ \hline Number of breakdowns & 0 & 1 & 2 & 3 & 4 & 5 & 6 \\ Number of years in which breakdowns occurred & 1 & 3 & 5 & 5 & 3 & 3 & 0 \\ \hline \end{tabular} We need to calculate the expected number of breakdowns for which the relationship is: Expectednumberofbreakdowns=(Numberofbreakdowns)(correspondingfrequency) Based on the given information, the frequency for each of the breakdowns = Observed Breakdowns / Total Observations. First calculate the frequency for each number of breakdowns to use in the relationship. For the observation with 2 breakdowns, the corresponding frequency is (round your response to two decimal places). For Niagara Falls, the expected total number of breakdowns is (round your response to two decimal places)
