=1. The height of male giraffes follows a normal distribution with µ 18 feet and o= 0.9 feet².(a) What is the probability that a male giraffe has a height between 19 and 22 feet? Write outthe solution in integral form and use the following R code to compute the numerical answer:pnorm (22, 18,0.9) - pnorm(19, 18,0.9).(b) What height would a male giraffe need to be in order to be in the top 10 percent? Write out theequation we would need to solve in order to answer this question, then use the qnorm() function inR to find this score.(c) What is the probability that a male giraffe will grow shorter than 16 feet.(d) The tallest male giraffe in the world is measured to be 21 feet according to the Guinness WorldRecords. What is the probability that a giraffe would grow higher than 21 feet.

Hi! Thank you for the question. As per the honor code, we are allowed to answer three sub-parts at a…

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 48 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 σ = 8.00 ml/kg for the distribution of blood plasma. When finding an 99% confidence interval, what is the critical value for confidence level? (Give your answer to two decimal places.)
