The U.S. Health Department reported that 40% of households had both a wireless phone and a landline. Assume that in a simple random sample of 300 households, 105 are found to have both services. With this information answer the following questions: What is the population proportion, π? What is the sample proportion, p? What is the standard error of the sample proportion? In the sampling distribution of the proportion, what is the probability that a sample of this size would result in a sample proportion at least 35%?

An appliance dealer sells three different models of upright freezers having 13.5, 15.9, and 19.1 cubic feet of storage space. Let x = the amount of storage space purchased by the next customer to buy a freezer. Suppose that x has the following probability distribution: x 13.5 15.9 19.1 P(X=x). .2 .5 .3 Calculate the mean and standard deviation of the random variable. Interpret the mean in context. If the price of the freezer depends on the size of the storage space, x, such that Price = 25x – 8.5, what is the mean value of the variable Price paid by the next customer? What is the standard deviation of the price paid?
