A recent CBS News survey reported that 69% of adults felt the U.S. Treasury should continue making pennies.

Suppose we select a sample of 14 adults.

How many of the 14 would we expect to indicate that the Treasury should continue making pennies? (round your answer to 2 decimal places)

What is the standard deviation? (round your answer to 4 decimal places)

What is the likelihood that exactly 8 adults would indicate the Treasury should continue making pennies? (round your answer to 4 decimal places)

What is the likelihood at least 8 adults would indicate the Treasury should continue making pennies? (round your answer to 4 decimal places)
