According to the Center for Disease Control (CDC) during the 2018-2019 season the percent of Americans 18 and older who had a flu shot was 45.3%. We did a random sample of 500 Americans and found that 200 out of the 500 had a flu shot. Is there enough evidence at the 5% level that 45.3% or less of Americans 18 or older had a flu shot? Check the conditions: a) Condition 1: Random- Stated, Condition 2: All Americans > 10(500) = 5000, Condition 3: (500)(0.453) = 225.5 > 10 and (500)(1-0.40) = 300 b) Condition 1: Random- Stated, Condition 2: All Americans 18 and older > 10(500) = 5000, Condition 3: (500)(0.453) = 226.5 > 10 and (500)(1-0.453) = 273.5 > 10 c) Condition 1: Random- Stated, Condition 2: All Americans > 10(0.453) = 45.3, Condition 3: (500)(0.453) = 225.5 > 10 and (500)(1-0.453) = 273.5 d) Condition 1: Random- Stated, Condition 2: All Americans 18 and older> 10(500) = 5000, Condition 3: (500)(0.40) = 200 > 10 and (500)(1-0.40) = 300 > 10
