The least-squares regression equation is y = 660.0x+ 16,178 where y is the median income and x is the percentage of 25 years and older with at least a bachelor's degree in the region. The scatter diagram indicates a linear relation between the two variables with a correlation 55000- coefficient of 0.7262. Complete parts (a) through (d). 25000- 15 20 25 30 35 40 45 50 55 60 Bachelor's % ..... (a) Predict the median income of a region in which 30% of adults 25 years and older have at least a bachelor's degree. $ (Round to the nearest dollar as needed.) (b) In a particular region, 25.9 percent of adults 25 years and older have at least a bachelor's degree. The median income in this region is $36,518. Is this income higher than what you would expect? Why? This is V than expected because the expected income is $ (Round to the nearest dollar as needed.) Median Income
