7. Studies suggest hunter discarded viscera of big game animals is a source of lead available to scavengers. Bedrosian et al investigated the incidence of lead exposure in bald eagles in Wyoming during the big game hunting season. From a sample 61 adult eagles' blood lead level (ug/dl), the mean i = 95.63 and standard deviation, s = 132.3. (a) The distribution of the amount of lead is strongly skewed. Is it skewed left or right? Explain your answer. (b) Give a 95% confidence interval for the mean of blood lead in this population of adult eagles. (c) Any amount above 60 pg/dl is considered clinically affected. Give an appropriate hypothesis test to see if the mean blood level is above this benchmark. (d) Determine the value of the test statistic and estimate the p-value. A G (e) Use the p-value to state your conclusions about lead exposure in bald eagles in Wyoming
