The table shows the total number of student applications to universities in a particular state over a period of 12 semesters. States base their decisions on data like this. Suppose the decide that if fewer than 200,000 students apply during 6 or more semesters, the state will make a special effort to promote university education. Using this data, what is the population proportion of semesters for which the number of student applications is less than 200,000?
Question
Answer:
There are 12 semesters. Since it's in thousands, 106 becomes 106,000, 137 is 137,000, etc., making everything over 200 in the data table over 200,000. Therefore, 7 out of the 12 are over 200,000, making the population proportion 7/12 for over 200,000. Since there are none exactly at 200,000, everything else is under 200,000. To get the population proportion for that, we do 1-7/12=12/12-7/12=5/12
