Computer output for fitting a simple linear model is given
below. State the value of the sample slope for this model and give
the null and alternative hypotheses for testing if the slope in the
population is different from zero. Identify the p-value and use it
(and a 5% significance level) to make a clear conclusion about the
effectiveness of the model.

Test the given claim. Identify the null hypothesis,
alternative hypothesis, test statistic, P-value, and then state
the conclusion about the null hypothesis, as well as the final
conclusion that addresses the original claim. Among 2031 passenger
cars in a particular region, 227 had only rear license plates.
Among 300 commercial trucks, 45 had only rear license plates. A
reasonable hypothesis is that commercial trucks owners violate laws
requiring front license plates at a higher rate than owners of
passenger cars....

8.3.16-1 WS A data set lists earthquake depths. The summary statistics are n = 600, x = 5.71 km, s = 4.73 km. Use a 0.01 significance level to test the claim of a seismologist that these earthquakes are from a population with a mean equal to 5.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test...
