1. Years of formal education appears to be related to income.
From a sample of 60 people, b1 = .02, the standard error of
estimate is 10.52 and sx 2 is 13641. Using a 5% level of
significance and a hypothesis test for the slope, is there a linear
relationship between the two variables?

related, data was collected from 125 households and the correlation
coefficient for the two variables was...

A researcher is interested in whether the number of years of
formal education is related to a person's decision to never smoke,
continue to smoke, or quit smoking cigarettes. The data below
represent the smoking status by level of education for residents of
the United States 18 years or older from a random sample of 350
residents. Round all numeric answers to four decimal places.

The standard deviation of test scores on a certain achievement
test is 10.9. A random sample of 60 scores on this test had a mean
of 72.5. Based on this sample, find a 90% confidence interval for
the true mean of all scores. Then complete the table below. Carry
your intermediate computations to at least three decimal places.
Round your answers to one decimal place. (If necessary, consult a
list of formulas.)

To test Ho: ? = 400 versus H1: ? > 400, a simple random
sample of n = 100 is obtained. Assume the population standard
deviation is 80. If the researcher decides to test this hypothesis
at the ?? = .05 level of significance, compute the probability of
making a Type II Error if the true population mean is 420. What is
the power of the test?

A random sample of 400 men and 400 women was randomly selected
and asked whether they planned to attend a concert in the next
month. The results are listed below. Perform a homogeneity of
proportions test to test the claim that the proportion of men who
plan to attend a concert in the next month is the same as the
proportion of women who plan to attend a concert in the next month.
Use α = 0.04.
