Question:
Suppose that the downtime in seconds of the WiFi for the college is distributed according to the gamma distribution, with shape parameter 3 and scale parameter 4.
Solve the following:
a) What is the probability that the daily downtime is exceeded 1.5 standard deviations from its expected value?
b) What is the probability that the daily downtime is between 2 and 4 seconds?
c) What is the probability that X > 3?
d) If X 1 ,X 2 ,X 3 ,X 4 ,X 5 are the downtimes of each of the 5 days of the workweek, and if daily downtimes are independent of one another then what is the probability that X 1 ,X 2 ,X 3 ,X 4 ,X 5 are all greater than 4 seconds?
e) What is the probability that X < 2?
