Question
A local hospital historical records were kept on the number of times a specific CT scanner was serviced in a given year. Using the information
A local hospital historical records were kept on the number of times a specific CT scanner was serviced in a given year. Using the information a probability distribution was created letting the random variable x represents the number of times the CT scanner was serviced in a year long period
X= 0 P(X)= .20
X=1 P(X)=.40
X=2 P(X)=.25
x=3 P(X)=.10
x=4 P(X)=.05
NOT THERE HAS NEVER BEEN A YEAR THAT CT SCANNER WAS SERVICED MORE THAN 4 TIMES
a. The probability that over the next year the CT scanner will need to be serviced at least 2 times.
b. Determine the mean and standard deviation of this random variable
c. Given that it costs the hospital $500 each time the Ct Scanner is serviced please determine the average servicing cost the hospital can expect to incur from this scanner over the next year/
