. Wildlife biologists inspect 153 deer taken by hunters and find 32 of them carrying ticks that test positive for Lyme disease.

a) Construct and interpret a 90% confidence interval for the percentage of deer that may carry such ticks. Show all work and formulas.

b) If the wildlife biologists would like to cut the margin of error found in part (a) to 2.5%, how many deer must they inspect? (Keeping the same level of confidence)

c) What concerns, if any, do you have about how the sample the wildlife biologists used was collected?

why do you think the deer population was only 4,00 in 1905 when the carrying capacity of the rangeland could support 30,000 deer or more. I don't understand why a population could be so far below the carrying capacity.
