Answer: 
Explanation:
If r is the number of successes out of n trials , then the sample proportion of success = 
For binomial experiment , if the population probability of success p on a single trial is not given , then the best point estimate for probability of success p on a single trial is the sample proportion of successes.
i.e. a point estimate for the probability of success p on a single trial :

Hence, a point estimate for the probability of success p on a single trial = 
Savings account is what would go in the blank.
Answer:
The Total manufacturing costs will increase while the unit manufacturing costs will decrease
Explanation:
The most likely behavior of the total manufacturing costs as well as the unit manufacturing costs is that the Total manufacturing costs will increase while the unit manufacturing costs will decrease because Atlas Manufacturing has the capacity to produce 50,000 valves annually which is per year in which it produces 40,000 valves and is about to increase the production to 45,000 valves the next coming year which will cause the manufacturing costs to increase and inturn cause the unit manufacturing costs to decrease.
Answer: 
Explanation: A supply equation shows us the mathematical relationship between quantity supplied and the price of the good. Since price and supply are positively related, P must carry a positive sign in the supply equation.
Given, supply is Qs=4P - 24
P is the price paid by consumers in the market.
When a $3 tax is levied , price sellers receive becomes P-T = P - 3
So, the new supply equation will be
