gyptian fruit bats in the wild commonly eat loquats, figs and wild dates. A researcher wanted to see whether Egyptian fruit bats showed any preference among these three types of fruit. To test that, the researcher collected a sample of 60 fruit bats. Each bat was given an opportunity to select one of the three types of fruit, and its choicewas recorded. The following frequencies were observed: Loquats             Figs                    Wild dates 12                      25                       23 Another researcher wanted to use the data above to test whether there was a relationship between the bats’ food preference and their sex (male/female). Which statistical test should this researcher use to answer her question? Explain your answer

An article about the California lattery gave the following information on the age distribution of adults in California: 35% are between 18 and 34 years old, 51% are between 35 and 64 years old, and 14% are 65 years old or older. The artide also gave Information on the age distribution of those who purchase lottery tickets. The following table is consistent with the values given in the article. Suppose that the data resulted from a random sample of 200 lattery ticket purchasers. Based on these sample data, is it reasonable to condude that ane or more af these three age groups buys a disproportionate share of lottery tickets? Use a chi-square goodness-of-fit test with a- 0.05. (Round your answer to two decimal places.) Age of Purchaser Frequency 18-34 45 35-64 100 65 and over 55 P-value interval Op
