The size of the raccoon population at a national park last year was 180.
The size of the raccoon population at a national park last year was 180. This year, the population is 189. If the population increases exponentially, find the population of raccoons in 4 years. Use P = P0ekt where P0 represent the initial population. Round to the nearest whole number.

The health of the bear population in
Yellowstone National Park is monitored by
periodic measurements taken from
anesthetized bears. In a sample of 100 bears, the mean weight was
found to be 185 lbs. Assume that ơ (population
standard deviation) is known to be 125 lbs, use a 0.03 significance
level to test the claim that the population mean weight of bears is
equal to 210 lbs.
State the claim in symbolic form.
