Dr. Lillian Fok, a New Orleans psychologist, spe-cializes in treating patients who are agoraphobic (i.e., afraid to leave their homes). The following table indicates how manypatients Dr. Fok has seen each year for the past 10 years. It alsoindicates what the robbery rate was in New Orleans during thesame year: Using trend (linear regression) analysis, predict the number ofpatients Dr. Fok will see in years 11 and 12 as a function of time.How well does the model fit the data?

The following gives the number of accidents that occurred on Florida State Highway 101 during the last 4 months: Month Jan Feb Mar Apr Number of Accidents 25 45 60 105 Using the least-squares regression method, the trend equation for forecasting is (round your responses to two decimal places): y = - 5 + 25.5 x Using least-squares regression, the forecast for the number of accidents that will occur in the month of May = 122.5 accidents (enter your response as a whole number).
