5. In a population of the Eastern starling, there are 5000 nests with young. The distribution of brood size (number of young in a nest) is given in the accompanying table. BROOD SIZE FREQUENCY (NUMBER OF BROODS) 90 230 610 1400 1750 750 130 1 2 3 4 5 6 7 8 9 10 TOTAL 26 3 1 5000 What is the median brood size in the data set? (2 points) 6. Health care practitioners wanted to know whether the mean body temperature of patients with a particular disease differed significantly from 98.6 °F. They used a random sample of 25 patients for their study. They conducted the appropriate test and got a P value of 0.58. Based on this result, what value do you know falls within the 95% confidence interval for mean body temperature of this sample? (Your answer must be an actual number.) [2 points)
