college professor never finishes his lecture before the end of the hour and always finishes his lectures within 3 min after the hour. Let X = the time that elapses between the end of the hour and the end of the lecture and suppose the pdf of X is as follows.

f(x)= kx^2 0 less than or equal to x less than or equal to 3 otherwise f(x)=0

a) find the value of K that satisfy condition of PDF?

b) find cdf (cumulative distributive function) for f(x)

c) what is the probability that the lecture ends at t=0.5min of the end of the hour?

also explain how you would put it in a calculator using normpdf/binompdf or normcdf/binomcdf

Expert Solution

In the above pictures, the value of 'k' for which the function f(x) follows the condition for a pdf is given and also the CDF and the value of PDF at time=0.5min is given. Also the procedure for the calculation using TI-83 calculator of the third part of the problem is given. Hope you will like it. Thank you.
