Question

In Module 4 Part 4, you created a contingency table based on the hiking preferences of surveyed individuals. (See page 62 of the updated notes for Module 4.) Suppose this survey group was expanded to include 12 more hikers. The additional data is as follows: 9 additionally surveyed female hikers prefer hiking near streams 3 additionally surveyed male hikers prefer hiking in the mountains Update the table from your notes with the information given above. Then answer the questions. Hiking Location Preference Mountains Woods Streams Female 13 21 25 59 Male 20 18 25 63 33 39 50 122 Find the requested probabilities. Round all probabilities to four decimal places. What is the probability that a randomly selected hiker is male? P(Male) = What is the probability that a randomly selected hiker prefers hiking in the mountains? P(Prefers Mountains) = What is the probability that a randomly selected hiker is male or prefers hiking in the mountains? P(Male or Prefers Mountains) = Suppose you select a female hiker at random. What is the probability that she prefers hiking near streams? P(Prefers streams | Female) =
