If the length of time required by students to complete a 1-hour exam is a random variable with a pdf given by cx² + x if 0≤x≤1 fx(x) = LARI then what is the probability a student finishes in less than a half hour? Also, calculate the variance of this distribution. [6 MARKS] otherwise ii. If a random variable X has the probability density function (pdf) e-2 for <2 f(x) = then what is the 75th percentile of X? otherwise, [5 MARKS] If the length of time required by students to complete a 1-hour exam is a random variable with a pdf given by cx² + x if 0≤x≤1 fx(x) = LARI then what is the probability a student finishes in less than a half hour?
