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."

Thus, a higher price earnings ratio will lead investors to infer that the firm's stock is overvalued and one should consider selling the stock.
Answer:
the quantity supplied is to a change in price.
Explanation:
Elasticity of supply measures the degree of responsiveness of quantity supplied to changes in price
Elasticity of supply = percentage change in quantity supplied/ percentage change in price
Supply is elastic if a small change in price has a greater effect on the quantity supplied.
Supply is inelastic if a small change in price has little or no effect on quantity supplied.
Supply is unit elastic if a small change in price has a proportional equal effect on quantity supplied.

Answer:
Gives equal weight to all cash flows arriving before the cutoff
Explanation:
The payback period measures how long it takes for the amount invested in a project to be recovered from a project.
A project with a shorter pay back period is favoured over projects with longer payback periods.
The payback period gives equal weights to all cash flows before arriving at a cut Off. The discounted payback period remedies this by discounting cash flows.
