  1. (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 and variance 1. Express your answer in terms of Φ, and then use software of your choice to evaluate it. (Hint: Compute the mean and standard deviation of the total insurance claim placed in a year. By the central limit theorem, the total insurance claim is approximately normally distributed. Why?)

The central limit theorem states that: Populations with more than 30 observations are approximately normally distributed. As the sample size increase, a sampling distribution will look more and more like the population. As long as the sample size collected is at least 30, the variable of interest will always be approximately normally distributed. A skewed-left population can never be a sampling distribution that is approximately normally distributed. For sufficiently large random samples, the sampling distribution of the sample mean is...

1. The Central Limit Theorem for the proportion requires np >= 10 and n(1-p) >= 10, and that the sample was collected using an SRS. If these requirements are met, then the distribution of the sample proportion is approximately normal. If we know that the population proportion is p, what are the mean and standard deviation for the distribution of the sample proportion? Assume you know that n = 1002 and p = .50. Use this information in problems 2-4....
