Question

The McClatchy News Service reported on a sample of prime-time television hours. The
following table summarizes the information reported for two networks.
Network Mean Number of Violent Acts per Hour
ABC 15.6
FOX 11.7
Suppose that each of these sample means was computed on the basis of viewing n = 50 randomly
selected prime-time hours.
(1) Suppose we want to compare the true mean number of violent acts per prime-time hour
between ABC and FOX. What is the population parameter of interest? What is the notation
for the parameter? Give a point estimate for the parameter.
(2) Suppose the estimated standard error of the point estimate from its bootstrap distribution is
1.4. Give a 95% confidence interval for the population parameter and interpret the
confidence interval.
(3) The National Coalition on Television Violence claims that shows on ABC are more violent
than on FOX. Based on the confidence intervals from part (2), do you agree with this
conclusion? Explain.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
