-Based on the Excel output in Figure 5.2,you should conclude that a

• A)one percentage point increase in the percentage of adults with a Bachelor's degree is associated with a statistically insignificant 40.59 percent increase in the obesity rate,holding all else constant.
• B)one percentage point increase in the percentage of adults with a Bachelor's degree is associated with a statistically significant 40.59 percent increase in the obesity rate,holding all else constant.
• C)one percentage point increase in the percentage of adults with a Bachelor's degree is associated with a statistically insignificant .466 percentage point increase in the obesity rate,holding all else constant.
• D)one percentage point increase in the percentage of adults with a Bachelor's degree is associated with a statistically significant .466 percentage point increase in the obesity rate,holding all else constant.
