I need help with my homework. need explanation and answer ASAP.

According to the Centers for Disease Control and Prevention (CDC), only 22.9% of American adults between the age of 18 and 64 met the 2008 guidelines for both aerobic and muscle-strengthening exercises between 2010 and 2015. Suppose a simple random sample of 200 American adults were asked about their exercise habits (assume the sample was studied in 2015). Let X be the number of adults in our sample who met the 2008 guidelines for both aerobic and muscle- strengthening exercises. Select all the following that are true: We can use a normal approximation to the binomial distribution for X since... C] the adults in our sample are independent. C] up: 10andnq2 10 C] we have a simple random sample from the population. According to the Centers for Disease Control and Prevention (CDC), only 22.9% of American adults between the age of 18 and 64 met the 2008 guidelines for both aerobic and muscle-strengthening exercises between 2010 and 2015. Suppose a simple random sample of 200 American adults were asked about their exercise habits and assume the sample was studied in 2015. Let X be the number of adults in our sample who met the 2008 guidelines for both aerobic and muscle-strengthening exercises. Using the distributional assumptions of X from the previous question, match the following: The expected number of individuals who met the 2008 guidelines for both aerobic [ Choose ] and muscle-strengthening exercises in our sample. The variance of the number of individuals who met the 2008 guideline [ Choose ] 35.312 for both aerobic and muscle- 5.942 strengthening exercises in our sample. We cannot compute it from the information provided. 0.229 45.8 0.000883 200
