Suppose 20% of all television viewers in the country watch a particular program.
a. For a random sample of 2500 households measured by a rating agency, describe the frequency curve for the possible sample proportions who watch the program.
b. The program will be canceled if the ratings show less than 17% watching in a random sample of households. Given that 2500 households are used for the ratings, is the program in danger of getting canceled? Explain.
c. Draw a picture of the possible sample propor­tions, similar to Figure 19.3. Il lustrate where the sample proportion of .17 falls on the picture. Use this to confirm your answer in part (b).
