Fifty percent of Americans believed the country was in a recession, even though technically the economy had not shown two straight quarters of negative growth. For a sample of 20 Americans, make the following calculations.
a. Compute the probability that exactly 12 people believed the country was in a recession.
b. Compute the probability that no more than five people believed the country was in a recession.
Can someone help me with c and d?
c. How many people would you expect to say the country was in a recession?
would this be pp(1-p)?
d. Compute the variance and standard deviation of the number of people who believed the country was in a recession.
Would I use the number 12 from the people above?
