Answer:
The store manager is 95% confident that the average amount spent by all customers is between $ 31.84 and $ 38.66.
Explanation:
In statistics, a confidence interval is the probability that the parameter of a population lies between two set of values when a random sample of the population is drawn for a specific percentage of times. This means that the confidence interval is formed about the whole population not the sample from which it is calculated.
The probabilities of a confidence interval can take any number, but 95% and 99% confidence level that are usually used.
It should be noted that, for example, 95% confidence level implies that there is a 95% chance that the true mean of the population lies within the calculated confidence interval.
Therefore, the statement which gives a valid interpretation of the interval in the question is the first one which states that "the store manager is 95% confident that the average amount spent by all customers is between $ 31.84 and $ 38.66."

Answer:
$10,340
Explanation:
The computation of k is shown below;
Rate per quarter = 6% ÷ 4 = 1.5%
In the case when perpetuity paid every year, the effective rate is
= (1 + 1.5%)^4 - 1
= 6.136%
Now Effective rate in the case when perpetuity paid every 5 years
= (1 + 1.5%)^(4 × 5) - 1
= 34.68%
Now
The present value of Both perpetuities = $6,500 ÷ 6.13635506249994% + $8,500 ÷ 34.6855006550052%
= $130,431.99
Now
annuity =k
Number of Periods=25
effective rate = 6.13635506249994%
Annuity k =PV ÷ ((1 - (1 + r)^-n) ÷ r
= $130,431.99 ÷ ((1-(1 + 6.13635506249994%)^-25) ÷ 6.13635506249994%
= $10,335.84
= $10,340
