Chapter 10.2, Problem 14E
Are nursing salaries in Tampa, Florida, lower than those in Dallas, Texas? As reported by the Tampa Tribune, salary data show staff nurses in Tampa earn less than staff nurses in Dallas. Suppose that in a follow-up study of 40 staff nurses in Tampa and 50 staff nurses in Dallas you obtain the following results.
- a. Formulate a hypothesis so that, if the null hypothesis is rejected, we can conclude that salaries for staff nurses in Tampa are significantly lower than for those in Dallas. Use α = .05.
- b. What is the value of the test statistic?
- c. What is the p-value?
- d. What is your conclusion?

We are intrested in predicting the percentage of people commuting to work by walking given some input variables. Each observation corresponds to a different city and each input variable summarizes some characteristic of a given city, such as density, urban sprawl and average income per capita. This is
1.
not a machine learning problem. Only social scientists would be interested in such a problem.
2.
both a classification and a regression problem as it depends on the way one codes the output variable as either 0, 1 or a a particular number in the [0,1] interval.
3.
a regression problem. The output variable is continuous.
4.
a classification problem. Walking to work is a discrete variable and can only take two values: to walk to work and not to walk to wor
