QUESTION 14Let X represent the width and Y represent the length of rectangular panels used for interior doors (in inches). Suppose X is normally distributed with a mean of 20 inches and standard deviation of 1.2 inches, and Y is normallydistributed with a mean of 4 inches and a standard deviation of 0.65 inches. Furthermore, the covariance between X and Y is 0.325. Consider the perimeter of a panel - that is, consider 2 X+2 Y.Which of the computations below is the proper way to calculate the variance?O A. V(2X + 2Y) = (2)(1.2)2 + (2)(0.65)2 + (2)(2)(2)(0.325)O B. V(2X + 2Y) = (2)(1.2)2+(2)(0.65)2 + 0.325OC. V(2X + 2Y) = (4)(1.2)2 + (4)(0.65)2+(2)(2)(2)(0.325)O D. V(2X + 2Y) = (4)(1.2)2 + (4)(0.65)2 +0.325

It is given that- Standard deviation of x: σx=1.2 Standard deviation of y: σy=0.65 Covariance…

Answered: Let X represent the width and Y…

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 46 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 ? = 7.80 ml/kg for the distribution of blood plasma. (d) Find the sample size necessary for a 99% confidence level with maximal margin of error E = 2.90 for the mean plasma volume in male firefighters. (Round up to the nearest whole number.) ________ male firefighters

If the iron cutting machine in a factory works continuously for a certain period of time under the same conditions, it goes into malfunction. In this type of failure, the machine takes 24 hours to cool down. After the machine has cooled down, it continues to work the next day. Assume that the running time (minutes) of this machine until it malfunctions has a normal distribution. The working time of the iron cutting machine until the failure was measured for 9 different days, which were chosen at random. Continuous working time (minutes): 14-26-18-29-12-19-22-30-19 a) Establish the 95% confidence interval for the average uninterrupted working time of this iron cutting machine and interpret the result.b) The factory chief claims that the average continuous operating time of the machine is less than 23 minutes. Test the claim that the average continuous working time of this iron cutting machine is less than 23 minutes at the 0.05 significance level and the result isPlease comment.
