The population of a given age group can be found by integrating this function over the interval for that age group. (a) Find the integral over the interval (0,9). (Round to the nearest integer as needed.) What does this integral represent? O A. The total number of people in this area under 9 years old was about 236 in 2010 OB. About 236 million people aged 0 to 90 have ever lived in this area from year o through 2010 OC. The number of people in this area increased by about 236 million people aged 0 to 90 in 2010 OD. The total number of people in this area aged 0 to 90 was about 236 million in 2010. (b) Find the number of people alive in 2010 that were born in the seventies, that is, those in the range of 2 to 3 decades in 2010 million (Round to the nearest Integer as needed.)
