Tutorial 4: Estimations 1. A process producing bricks is known to yield output whose weights are normally distributed with a standard deviation of 0.12lb. A random sample of 40 bricks from a day’s output had a mean weight of 4.07lb. (i) Find a 99% confidence interval for the mean weight of all bricks produced on that day. (ii) Estimate the smallest sample size required if the error in estimating the population mean weight of all bricks is to be within 0.03lb with 95% confidence.

Mathematics Department Tutorial Sheet No. 3 MAL250(Probability and Stochastic Processes) 1. The percentage of alcohol (100X ) in a certain compound may be considered as a random variable‚ where X (0 < X < 1) has pdf fX (x) = 20x3 (1 − x)‚ 0 < x < 1. Suppose that the selling price of the above compound depends on the alcohol contents. Specifically‚ if 1/3 < X < 2/3‚ the compound sells for c1 dollars/gallon otherwise it sells for c2 dollars/gallon. If the cost is c3 dollars/gallon‚ find the probability
