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."

The national saving equal to
= Private saving + public saving

= $255 billion
And, the public saving would be -$150 billion
So, the national saving would be
= $255 billion - $150 billion
= $105 billion
