Two summers ago, Mrs. Pugawko saw a female black bear on a trail in Olympic National Park and was shocked with how large the bear appeared. The park ranger told her that there are 2,852 adult female black bears that are tracked and tagged in the national park. A random sample of 45 female black bears from those tagged had an average body weight of 204 pounds with a standard deviation of 26 pounds. A. Construct and interpret a 95% confidence interval to estimate the true population mean weight of all female bears that are tagged.

B. How big of a sample size should the ranger take if he wantsh is margin of error to be no more than 7 pounds?

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
