Question

Use a 0.01 significance level to test the claim that the mean amount of time spent watching television by women is smaller than the mean amount of time spent watching television by men.

Test the indicated claim about the means of two populations.
Assume that the two samples are independent simple random
samples selected from normally distributed populations. Do not
assume that the population standard deviations are equal.
A researcher was interested in comparing the amount of time (in
hours) spent watching television by women and by men.
Independent simple random samples of 14 women and 17 men were
selected, and each person was asked how many hours he or she had
watched television during the previous week. The summary statistics
are as follows.
Women
x1 = 12.5 hr x2 =13.8 hr
Men
s1 = 3.9 hr
52 = 5.2 hr
nį = 14
n2 = 17
Use a 0.01 significance level to test the claim that the mean
amount of time spent watching television by women is smaller than
the mean amount of time spent watching television by men.

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 + ...
