The least-squares regression equation is y=663.3x + 16,436 where y is the median income and x is he percentage of 25 years and older with at least a bachelor's degree in the region. The scatter iagram indicates a linear relation between the two variables with a correlation coefficient of 7015. Complete parts (a) through (c). 550001 20000+ 15 20 25 30 35 40 45 50 55 60 Bachelor's % Q Q a) Predict the median income of a region in which 25% of adults 25 years and older have at least a bachelor's degree 33,019 (Round to the nearest dollar as needed.) b) In a particular region, 25.5 percent of adults 25 years and older have at least a bachelor's degree. The median income in this region is $36,619. Is this income higher than what you would e Why? This is higher than expected because the expected income is $ 33,350
