A light fixture contains five lightbulbs. The lifetime of each bulb is exponentially distributed with mean 199.0 hours. Whenever a bulb burns out, it is replaced. Let T be the time of the first bulb replacement. Let X1, i = 1, . . . , 5, be the lifetimes of the five bulbs. Assume the lifetimes of the bulbs are independent. 1. Find P( X1 > 100). (Round the final answer to four decimal places.) 2. Find P( X1 > 100 and X2 > 100 and • • • and X5 > 100). (Round the final answer to four decimal places.) 3. Find P(T ≤ 100). (Round the final answer to four decimal places.) 4. Let t be any positive number. Find P(T ≤ t), which is the cumulative distribution function of T. 5. Find the mean of T.

arget's annual revenue data from 2005 to 2021 are available for download. Make an Excel graph of the annual data, and fit three trends (linear, quadratic, and exponential) to the time series. Copy and paste the graph in the space below or attach the file. State the three trendline equations from part a and their R2 values. Which trend model do you think is the best one to use to forecast annual revenue? Choose only one model and explain the reasons for your choice. Use the model you chose in part c to forecast the annual revenue for 2022.
