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."
I wish you the best.
Hello!
Often people put up signs that, that person likes and is interested in. People also can bargain with a person. So if they are leaving because they think the product is to high of a price for them, then you can tell them you can lower the price.
( word of advice, this is a last resort option)
I hope it helps!
Answer: $24
Explanation:
Given that,
Two workers serve = 16 customers per hour
Three workers serve = 22 customers per hour
Each customer spends an average of $4 in the store.
Total revenue from Two workers = 16 × $4
= $64
Total revenue from Three workers = 22 × $4
= $88
Therefore, the marginal benefit of hiring the third worker would be:
= Total revenue from Three workers - Total revenue from Two workers
= $88 - $64
= $24
Answer:
The responses to the given question can be defined as follows:
Explanation:
For point a:
Car arrival time
Each car arrives at an interval of time of 
process time 
The number of vehicles moving in an hour equals 2 per hour.
As 
is greater than 1. The device will not work, resulting in such a revenue loss.
Within 44 minutes, a parking lot would be completely full, with only 1 person being serviced, and then the next empty slot would be completed 64 minutes later.
The system's production capacity is 8.5 per hour [a person entering at 0 will exit at 30]. The person that comes in at 4 will leave at 34. Roughly 50 customers would be supported for an hour.
For point b:
The number of customers would be 
for a 12-hour time frame.
Total cost=
The total number of customers to be served at an expense of 
customers.
