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 = 
Answer:
<em>It will take 9 months longer to repay this loan</em>
Explanation:
<u>Financial Loan Payments</u>
Let's assume a loan has been received for a present value PV at an interest rate i during n periods. Being R the amount of each payment, then

Solving for n we have

The first agreement of payment has the following data



Computing n


The new agreement changes R to 225, thus


This means that it will take 9 months longer to repay this loan
Saying that money is indivisible is false. As long as its not a penny, money can be divided down to the last cent
<span>In this case, Sara will see the ramen as a good that is more elastic in demand than will Sean. This will mean that, as income drops for Sara, she will purchase less of the good than will Sean. Sean will end up purchasing less of the good if he has an increase in income.</span>
