(Central Limit Theorem) An insurance company serves 10 large customers. The insurance claim placed by each customer in a year is uniformly distributed between 0 and 100. Assume that the insurance claims from different customers are independent. Use the central limit theorem to approximately compute the probability that the total insurance claim placed by all customers in a year exceeds 625. Let Φ(x) denote the cumulative distribution function of a standard normal distribution, i.e. a normal distribution with mean 0...

1. Are the following statements TRUE or FALSE?: (a) According to the Central Limit Theorem, given a large sample size (N > 30), then a normal probability plot of the same data would necessarily follow a straight line. (b) A 95% confidence interval for a population mean that does not include zero would also mean that a hypothesis test on the same data would yield a significant result at the .05 level. (c) The mean of a t-distribution with 5...

Two numbers, x and y, are selected at random from the unit interval [0, 1]. Find the probability that each of the three line segements so formed have length > 1 4 . For example, if x = 0.3 and y = 0.6, the three line segements are (0, 0.3), (0.3, 0.6) and (0.6, 1.0). All three of these line segments have length > 1 4 . hint: you can solve this problem geometrically. Draw a graph of x and...

Applying the Central Limit Theorem: The amount of contaminants that are allowed in food products is determined by the FDA (Food and Drug Administration). Common contaminants in cow milk include feces, blood, hormones, and antibiotics. Suppose you work for the FDA and are told that the current amount of somatic cells (common name "pus") in 1 cc of cow milk is currently 750,000 (note: this is the actual allowed amount in the US!). You are also told the standard deviation...
