Can you help me with both question 8.62 and 8.80? I'm not sure where to start. Any help would be appreciated

8.62 Crab spiders hiding on flowers. Refer to the Behavioral Ecology (Jan. 2005) experiment on crab spiders' use of camouflage to hide from predators (e.g., birds) on flowers, presented in Exercise 2.42. Researchers at the French Museum of Natural History collected a sample of 10 adult female crab spiders, each sitting on the yellow central part of a daisy, and measured the chromatic contrast between each spider and the flower. The data (for which higher values indicate a greater contrast, and, presumably, an easier detection by predators) are shown in the accompanying table. The researchers discovered that a contrast of 70 or greater allows birds to see the spider. Of interest is whether the true mean chromatic contrast of crab spiders on daisies is less than 70. 57 75 116 37 96 61 56 2 43 32 Based on Thery, M., et al.

This was one MUSIC of the questions of interest in a recent Pew Internet and od) 15American Life Project Survey (Oct. 2010). In a representa- tive sample of 755 adults who use the Internet, 506 stated -ni bas that they have paid to download music. Let p represent the true proportion of all Internet-using adults who have paid to download music. 001 A 8T.8 a. Compute a point estimate of p. b.
