For items number 2 through number 4, find the equation of the regression line and find the y value for the specified x value. Remember that no regression should be done when r is not significant. 2. Oil and Gas Prices. The average gasoline price per gallon (in citles) and the cost of a barrel of oi! are shown below for a random selection of weeks in 2015. oil ($) Gasoline ($) 1.97 |S1.91 60.65 59.56 52.86 45.12 44.21 1.96 2.06 2.04 2.00 1.99 Find the cost of gasoline when oil is $60 a barrel. 3. Measles and Mumps. The data show the number of cases of measles and mumps for a recent 5-year periot. Measles cases 43 140 71 63 212 Mumps cases 800 454 1991 2612 370 Given a year with 100'cases of measles, predict the expected number of cases of mumps for that year.

A random sample of classes revealed the following data. Find y when x= 12.
