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.
Answer:
1st question: false Refusing internal requests often calls for an indirect strategy. Providing adequate reasons and realistic alternatives helps maintain goodwill and a positive working environment.
2nd question: True. Refusals for routine requests should open with a buffer, a neutral statement on which both readerand writer can agree, and should transition into the reasons.
Answer:
![P(E1)=\frac{20}{50}=0.4](https://tex.z-dn.net/?f=P%28E1%29%3D%5Cfrac%7B20%7D%7B50%7D%3D0.4)
![P(E2)=\frac{13}{50}=0.26](https://tex.z-dn.net/?f=P%28E2%29%3D%5Cfrac%7B13%7D%7B50%7D%3D0.26)
![P(E3)=\frac{13}{50}=0.34](https://tex.z-dn.net/?f=P%28E3%29%3D%5Cfrac%7B13%7D%7B50%7D%3D0.34)
I used the relative frequency method
Explanation:
To solve this question we can use the relative frequency to find out each probability. The relative frequency is the ratio of the occurrence of each event and the total number of outcomes.
Here the experiment has been repeated 50 times, so that is the total number of outcomes and the denominator. There are 3 possible events E1, E2, and E3, so we can calculate the ratios to get the probabilities
Event E1 occurred 20 times of the 50: ![P(E1)=\frac{20}{50}](https://tex.z-dn.net/?f=P%28E1%29%3D%5Cfrac%7B20%7D%7B50%7D)
Event E2 occurred 13 times of the 50: ![P(E2)=\frac{13}{50}](https://tex.z-dn.net/?f=P%28E2%29%3D%5Cfrac%7B13%7D%7B50%7D)
Event E3 occurred 17 times of the 50: ![P(E3)=\frac{17}{50}](https://tex.z-dn.net/?f=P%28E3%29%3D%5Cfrac%7B17%7D%7B50%7D)
Answer:
B. people and community
Explanation:
Social responsibility is known as people and community. In other words it refers to any and all responsibilities that you may have when being part of a community or society to make that community better. This involves a wide range of responsibilities or obligations such as volunteering, cooperating with others, ethical and moral choices, etc. Anything that benefits the larger structure that you are part of would be considered a social responsibility.
