A sample survey of 59 discount brokers showed that the mean price charged for a trade of 100 shares at $50 per share was $33.75. The survey is conducted annually. With the historical data available, assume a known population standard deviation of $13,a. Using the sample data, what is the margin of error associated with a 90% confidence interval (to 2 decimals)?b. Develop a 90% confidence interval for the mean price charged by discount brokers for a trade of 100 shares at $50 per share (to 2 decimals).

In an effort to estimate the mean amount spent per customer for dinner at a major Atlanta restaurant, data were collected from 64 randomly selected customers. The sample mean was calculated as $27.75 with a sample standard deviation of $4. We wish to develop a 91% confidence interval for the mean amount spent per customer for dinner at this restaurant. Assume that the standard deviation of the amounts spent by ALL customers is $4.30. What is the variable of interest? ["", "", ""] And is this variable Quantitative or Qualitative? ["", ""] In other words: what is the one piece of info we care about for each individual in the population? Is it a quantitative measurement? Or do we determine if each individual belongs to a certain category (referred to as success) or not (failure)? If it is a quantitative measurement, then the population is filled with numbers. Otherwise, the population is filled with…
