You plan to conduct a marketing experiment in which students are to taste one of two different brands of soft drink. Their task is to identify the brand tasted. You select a random sample of 200 students and assume that the students have no ability to distinguish between the two brands. (Hint: if an individual has no ability to distinguish between the two soft drinks, then each brand is equally likely to be selected).

1. What is the probability that the sample will have between 50% and 60% of the identifications correct?
2. The probability is 90% that the sample percentage is contained within what symmetrical limits of the population percentage?
3. What is the probability that the sample percentage of correct identifications is greater than 65%?
4. Which is more likely to occur: more than 60% correct identifications in the sample of 200 or more than 55% correct identifications in a sample of 1,000? Explain

Assume that a population is normally distributed with a mean of 100 and a standard deviation of 15. Would it be unusual for the mean of a sample of 3 to be 115 or more? Why or why not?

The margin of error for polling results is typically determined as the half-width of a 95% confidence interval. With respect to a particular ballot proposition, a random sample of 423 voters indicated 51% support and 49% oppose the measure. What is the margin of error? Interpret the result.

Maternal smoking during pregnancy has been implicated in various problems with infant health.
Develop a research question on the health of babies born to smoking versus non-smoking mothers and devise a testable hypothesis related to this health issue. List as many problems as you can identify and anticipate in interpreting

Question 1:
Use the "Regression" function in Excel and (the data) of Visits: 3, 5, 4, 2, 1, 3, 6, 7, 4, 5, 10, 1, 2, 3, 8
Age 28, 45, 50, 19, 16, 27, 54, 63, 32, 42, 68, 19, 23, 30, 61, to estimate the linear relation between
the number of visits and the age of the patient. Examine the results of the analysis by

A firm wishes to assess the impact of changes in the market return on an assess that has a beta of 1.20
a. If the market return increased by 15%, what impact would this change be expected to have on the asset's return?
b. If the market return decreased by 8%, what impact would this change be expected to have on the asset's ret

A study of employees at a large company found a negative correlation between weight and distance walked on an average day. In other words, people who walked more weighed less. Would you conclude that walking causes lower weight? Can you think of an alternate explanation for the findings?

If investors in the United States and Canada require the same real interest rate, and the nominal rate of interest is 2 percent higher in Canada, what does this imply about expectations of U.S. inflation and Canadian inflation? What do these inflationary expectations suggest about future exchange rates?
