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?Set up the hypothesis test (Ho and Ha):a) Ho: u = 0.453 (The average of Americans who had flu shot is 45.3.)

Question

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?

Set up the hypothesis test (Ho and Ha):

a) Ho: u = 0.453 (The average of Americans who had flu shot is 45.3.) Ha: u < 0.453 (The average of Americans who had flu shot is less than 45.3.

b) Ho: p = 0.453 (The proportion of Americans who had flu shot is 45.3%.) Ha: p < 0.453 (The proportion of Americans who had flu shot is less than 45.3%.

c) Ho: p = 0.40 (The proportion of Americans who had flu shot is 40%.) Ha: p < 0.40 (The proportion of Americans who had flu shot is less than 40%.

d) Ho: p = 0.40 (The proportion of Americans who had flu shot is 40%.) Ha: p not equal to 0.40 (The proportion of Americans who had flu shot is not equal to 40%.)
