Part 2
We need to calculate the expected number of breakdowns for which the relationship is: Expected number of breakdowns equals Σ (Number of breakdowns × corresponding frequency).
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 = 0.20 (round your response to two decimal places).
Part 3
For Orlando Utilities, the expected total number of breakdowns = enter your response here (round your response to two decimal places).
