Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.)Z =P-value The recommended daily dietary allowance for zinc among males older than age 50 years is 15 mg/day. An article reports the following summary data on intake fora sample of males age 65-74 years: n =115, x = 12.7, and s = 6.84. Does this data indicate that average daily zinc intake in the population of all males age65-74 falls below the recommended allowance? (Use a =:0.05.)

Given information Sample mean x̅ = 12.7 mg/day Population mean µ = 15 mg/day Sample size = 115…

Answered: The recommended daily dietary allowance…

Isle Royale, an island in Lake Superior, has provided an important study site of wolves and their prey. Of special interest is the study of the number of moose killed by wolves. In the period from 1958 to 1974, there were 296 moose deaths identified as wolf kills. The age distribution of the kills is as follows;Age of Moose in Years Calf (0.5 yr)1-56-1011-1516-20 Number Killed By Wolves1065179546 (a) For each age group, compute the probability that a moose in that age group is killed by a wolf.
