A taxi company operates in two different regions, and it is analyzing the prices of rides in those regions. It has compiled the prices (in dollars) of 84 rides in each of the two regions during the last week. The histograms below show the distributions of the two data sets. Each histogram shows price (in dollars) on th horizontal axis and the number of taxi rides on the vertical axis. The means and standard deviations for the data sets are also given.

The company wants to use the Empirical Rule to make some approximations about both data sets. Unfortunately, it is appropriate to use the Empirical Rule on only one of them! Answer the parts below to help the company with their approximations. (a) Identify the data set for which it is appropriate to use the Empirical Rule. It is appropriate to use the Empirical Rule for the (Choose one) ▼ data set. For the data set identified in part (a), use the Empirical Rule to make the following approximations. (b) The percentage of rides costing between $9.82 and $41.42 is approximately (Choose one) (c) Approximately 99.7% of the rides cost between $ and $0. X
