In an industrial setting, process steam has been found to be normally distributed with an average value of 25,000 pounds per hour. There is an 80% probability that steam flow lies between 20,000 and 30,000 pounds per hour. What is the variance of the steam flow?

Find Var(X−3Y).
A variance function Var(Y IX = x) tells us: about the variability of Y at different values of X. O the extent to which Y and X are correlated. whether the mean function is linear or curved. O if a data point is an outlier.
Let X and Y be independent random variables representing the lifetime (in one billion years) of Type A and Type B stars, respectively. Both variables have exponential distributions, and the mean of X is 3 and the mean of Y is 11. What is the variance of the total lifetime of three times a Type A star and a Type B star?

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 7.97.9 parts/million (ppm). A researcher believes that the current ozone level is at an excess level. The mean of 2424 samples is 8.18.1 ppm with a variance of 0.250.25. Does the data support the claim at the 0.10.1 level? Assume the population distribution is approximately normal. Step 3 of 5: Specify if the test is one-tailed or two-tailed.
