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 \( T_2 \).

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.
Create a column of numbers going from 0 to 30. in binomial distrubution with n=30 and p=0.5. Remember that the variance is the expected value of the squared deviations from the mean. In the next column, compute the product of the probability of each outcome and the squared deviation from the mean. Place the sum of the 31 values in the cell next to the cell in which you have computed the variance as a function of the parameters.

Assume that a high school principal believes that high number of absences hinders the students' ability to perform on standardized tests. He randomly selects a sample of 9 students who had 5 or more absences in the school year. The average ACT Composite score for this sample is X = 19 with s = 4.9. ACT Composite scores are normally distributed with u = 21.0. Do the data support the claim that the high number of absences hinders the students' ability to perform on standardized tests, using a = .05? Please show the four-step hypothesis test. %3D
