Times/CNN voter polls monitor public opinion for the presidential candidates during 2000 presidential election campaign. One Time/CNN poll conducted by Yankelovich Partners Inc, used a sample of 589 likely voters. Assume the population proportion for a presidential candidate is p=.50. Let p be the sample proportion likely voters favoring the presidential candidate.
a. Show the sampling distribution of p
b. What is the probability the Times/CNN poll will provide a sample proportion within +-.04 of the population proportion?
c. What is the probability the Times/CNN poll will provide a sample proportion within +-.03 of the population proportion?
d. What is the probability the Times/CNN poll will provide a sample proportion within +-.02 of the population proportion?
A power of 0.2203 can be interpreted to mean there is a 22.03% chance of selecting a sample whose sample mean is larger than 166.3 lb.
The random variables, X and Y, have a probability density function given by: By transformation of variables, find the probability density function of Z=X+Y.
A process follows the binomial distribution with n = 8 and p = .3. Find
A local hardware store claims that the mean waiting time in line is less than 3.5 minutes. A random sample of 20 customers has a mean of 3.7 minutes with a standard deviation of 0.8 minute. If α = 0.05, test the store's claim.
