a-1. How many of the 18 would we expect to indicate that the Treasury should continue making pennies
a-2) What is the standard deviation?
a-3) What is the likelihood that exactly 3 adults would indicate the Treasury should continue making pennies?
Answer:
a-1
a-2
a-3
Step-by-step explanation:
From the question we are told that
The sample size is
The proportion of adult that felt the U.S. Treasury should continue making pennies is p = 0.64
The proportion of adult that feel otherwise is
The mean is mathematically evaluated as
substituting values
The standard deviation is mathematically represented as
substituting values
The likelihood that 3 adult would indicate the Treasury should continue making pennies is mathematically evaluated as
Now
substituting values
So
