Forecast the number of accidents that will occur in May,using least-squares regression to derive a trend equation.
Please forecast the mileage (in 100) for 2013 using a 4 period moving average method. Please keep 1 decimal place.
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?
