Transit Railroads is interested in the relationship between travel distance and ticket class purchased. A random sample of 200 passengers is taken. The table below shows the results. The railroad wants to know if a passenger’s choice in ticket class is independent of the distance they must travel.
| Traveling Distance | Third class | Second class | First class | Total | |
| 1-100 miles | 21 | 14 | 6 | 41 | |
| 101-200 miles | 18 | 16 | 8 | 42 | |
| 201-300 miles | 16 | 17 | 15 | 48 | |
| 301-400 miles | 12 | 14 | 21 | 47 | |
| 401-500 miles | 6 | 6 | 10 | 22 | |
| Total | 73 | 67 | 60 | 200 |
| d | What is the test statistic? | |

A hospital analyzed the relationship between the distance an
employee must travel between home and work (in 10s of miles) and
the annual number of unauthorized work absences (in days) for
several randomly selected hospital employees. The regression
analysis showed dfErr = 15, SSxx = 23.88,
SSyy = 130.00, and SSxy = -54.50.
What is the 99% confidence interval for β1 (with
appropriate units)?
a.
(-0.2651 days/mile, -0.1913 days/mile)
b.
(-2.6081 days, -1.9564 days)
c.
(-26.5130 days/mile, -19.1319 days/mile)
d....

Professor drives a Tesla to travel from city ? to city ?. The
distance between cities ? and ? is ? miles. The Tesla can go up to
? miles before it needs a charge and there are many charging
locations along the way including those in city ? and city ?.
Professor wants to minimize the number of charges needed so he can
get to his destination ASAP. Assume that at any charging location
there is at least another...
