A hobbyist family is making PPE (personal protective equipment) to donate to local health care workers.? Let • T1 ~ U(1, 4) be the amount of time (in hours) to 3D print a face mask and • T2 be an exponentially distributed random variable with an average of 3 hours to represent the time (in hours) to cut out and sew a suit. Describe the distribution of time to complete construction of one suit-and-mask outfit by computing the mean and standard deviation of the sum T+T, assuming independence between T1 and T2.

Question

Transcribed Image Text:A hobbyist family is making PPE (personal protective equipment) to donate to local health care workers.² Let
- \( T_1 \sim U(1,4) \) be the amount of time (in hours) to 3D print a face mask and
- \( T_2 \) be an exponentially distributed random variable with an average of 3 hours to represent the time (in hours) to cut out and sew a suit.
Describe the distribution of time to complete construction of one suit-and-mask outfit by computing the mean and standard deviation of the sum \( T_1+T_2 \) assuming independence between \( T_1 \) and \( T_2 \).
