Nielson Monitor-Plus, a service of Nielsen Media Research, is one of the leaders in advertising information services in the United States, providing advertising activity for 16 media, including television tracking, in all 210 Designated Market Areas (DMAs). One of the issues it has researched is the increasing amount of "clutter"-non-program minutes in an hour of prime time-including network and local commercials and advertisements for other shows. In 2004, the average non-programming minutes in an hour of prime-time broadcasting for network TV was 15:48 minutes. For cable TV, the average was 14:55 minutes.
a) Calculate the difference in the average "clutter" between network and TV.
b) Suppose the standard deviation in the amount of "clutter" for both the network and cable TV was either 5 minutes or 15 seconds. Which standard deviation would lead you to conclude that there was a major difference in the two "clutter" averages? Comment.
A large tank of fish from a hatchery is being delivered to a lake. The hatchery claims that the mean length of fish in the tank is 15 inches, and the standard deviation is 2 inches. A random sample of 36 fish is taken from the tank.
Explain probability distribution of X (name and parameters).
At a = 0.05, can you reject claim that at least 52% of adults are more probable to purchase a product when there are free samples?
The chi-square goodness of fit is______________a one-tailed test with the rejection region in the right tail.
Conduct the hypothesis test and compute the p-value. At a 0.05 level of significance, what is your conclusion?
Is it necessary to assume a normal distribution on the population to estimate the value of the mean spending per day? Explain.
Sampling distributions. Given a normal distribution with μ = 50 and standard deviation σ = 9, if a sample of n = 100 is selected.
Determine the distributions given below represent a probability distribution. Justify your answer.
Assume that the smiling time of eight-week old babies, in seconds, follows a uniform distribution between 0 and 23 seconds, inclusive. This means that any smiling time from 0 to and including 23 seconds is equally likely.
36 values given here are based on summary statistics from research by cumming. Do you think that these data are normally distributed?
We want to know if his support has decreased. In computing a test of hypothesis with , what is the estimate of the overall proportion?
