Question

I need help with letter c and d

23. Pitcher plants of the genus Nepenthes are typi- cally carnivorous, obtaining a great deal of their nutrition from insects that become trapped in the pitcher, die, and decay. N. lowi, a pitcher plant from Borneo, produces a second type of pitcher that attracts tree shrews (Tupaia mon- tana), which provide nutrients by defecating into the pitcher8 while they feed on a substance secreted by the plant. Based on measurements of 20 plants, Clarke et al. (2009) calculated a 95% confidence interval for the mean fraction of total leaf nitrogen in the plant species derived from tree shrews: 0.57< p<1.0. a. Does this result imply that individual plants receive between 57% and 100% of their leaf nitrogen from tree shrews? Explain. b. Is the confidence interval meant to bracket the sample mean or the population mean? c. Identify two values for the mean shrew frac- tion of total leaf nitrogen that the analysis suggests are among the most plausible. d. Identify two values for the mean shrew frac- tion of total leaf nitrogen that the analysis suggests are less plausible

Answer 1

Solution: c. Identify two values for the mean shrew fraction of total leaf nitrogen that the analysis suggests are among the most plausible.

Answer: Among the most plausible would be anything from $\dpi{100} 0.7$ to $\dpi{100} 0.8$. Because they are in the center of the given confidence interval.

d. Identify two values for the mean shrew fraction of total leaf nitrogen that the analysis suggests are less plausible.

Answer: The two values for the mean shrew fraction of total leaf nitrogen that the analysis suggests are less plausible are:

any value less than $\dpi{100} 0.57$ or greater than $\dpi{100} 1$.
