Advertising The effectiveness of a television commercialdepends on how many times a viewer watches it. After someexperiments an advertising agency found that if the effective-ness E is measured on a scale of 0 to 10, thenE(n) = }n – tu²where n is the number of times a viewer watches a givencommercial. For a commercial to have maximum effective-ness, how many times should a viewer watch it?

Given effectiveness as a function of no. of times a viewer watches a given commercialE(n) = 23n -…

Cardiovascular Disease Suppose the incidence rate of myocardial infarction (MI) was 5 per 1000 among 45- to 54-year-old men in 2000. To look at changes in incidence over time, 5000 men in this age group were followed for 1 year starting in 2010. Fifteen new cases of MI were found. 7.14 Of the 15 new MI cases in the preceding study, 5 died within 24 hours. Test whether the 24-hour case- fatality rate changed from 2000 to 2010.
Cardiovascular Disease Suppose the incidence rate of myocardial infarction (MI) was 5 per 1000 among 45- to 54-year-old men in 2000. To look at changes in incidence over time, 5000 men in this age group were followed for 1 year starting in 2010. Fifteen new cases of MI were found. Suppose that 25% of patients with Mi in 2000 died within 24 hours. This propartion is called the 24-hour case-fatality rate. Of the 15 new MI cases in the preceding study. 5 died within 24 hours. Test whether the 24-hour case- fatality rate changed from 2000 to 2010.

This activity demonstrates how to create graphics to enhance the presentation of quantitative data Scenario The sales manager for a small manufacturer is interested in marketing the company's rain coat line in a new area of the country. As a first step to establishing a marketing plan she has asked you to produce some graphs showing the market share of the products sold over the past several years in the region. Analysis After some research, you acquire the approximate sales for each of the competing products presently in the region under consideration (See the data given below). The question now is to show how best to organize the data to take advantage of a graphical analysis. Pie charts give a quick overview of the market share "slices” each competitor presently enjoys. So you decide to use a pie chart to graph the most recent year's sales data for the region. This will give a good indication of just who the market leaders are and how crowded it is at the top. Next, you decide to…

An agricultural field trial compares the yield of two varieties of corn. The researchers divide in half each of 8 fields of land in different locations and plant each corn variety in one half of each plot. After harvest, the yields are compared in bushels per acre at each location. The 8 differences (Variety A - Variety B) give x¯=3.07 and s=5.11. Does this sample provide evidence that Variety A had a higher yield than Variety B? (a) State the null and alternative hypotheses: (Type "mu" for the symbol μμ , e.g. mu > 1 for the mean is greater than 1, mu < 1 for the mean is less than 1, mu not = 1 for the mean is not equal to 1)H0 : Ha : (b) Find the test statistic, t = 7,6
