The approximate size of the initial population of the rats five years before is 89. With average of 1.4 growth rate per year, it accumulated to 478 rats over the 5 years time.
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 correct answer is 2. No overall change.
Explanation:
The aggregate demand is the total goods and services demanded by a country, at a certain price level, in a certain period of time.
The aggregate demand that can be accounted for measures exactly the same as GDP. So they are often used as synonyms.
To calculate aggregate demand, the same methods as for calculating GDP can be used, however, aggregate demand is associated with expenditure, so it is calculated by the product method, that is, from the point of view of what society has spent. This calculation takes into account the expenditure of families (private individuals), what has been spent on investment, the cost of public administrations, and finally, net exports, which is the difference between imports and exports In this way, the Aggregate Demand formula would look like this:
DA = C + I + G + (X-M)
