Complete Question:
A supervisor finds the mean number of miles that the employees in a department live from work. He finds x=2.9 and s=3.6. Which statement must be true?
z376 is within 1 standard deviation of the mean.
z37 is between 1 and 2 standard deviations of the mean.
z37 is between 2 and 3 standard deviations of the mean.
z37 is more than 3 standard deviations of the mean.
Answer:
z37 is between 2 and 3 standard deviations of the mean.
Explanation:
Standard deviation is a way of measuring of how much the value sample varies or disperses. A low standard deviation means that the values are near the mean value of the set, whereas a high standard deviation implies that the values are distributed over a wider range.
In reasonably average data sets, the values reflect about 68 per cent of the sample within 1 standard deviation from the mean; about 95 per cent in 2 standard deviations; and about 99.7 per cent within 3 standardized deviations.
Answer:
In that situation, the demand of the Milk tea will fall.
Explanation:
In businesses subtitles are the type of products that serve a similar purpose but generally less favorable. You use substitutes as a second product when you somehow cannot use the first/main product.
In the example above,
Let's say that Coffee is people's favorite beverages. They like it better than milk tea. But, if they don't have enough money to buy their favorite coffee, they sometimes have to exchange it and settle with milk tea.
When weather increases the harvest of the coffee bean crop, the price of coffee will most likely fall down due to the abundance in resource.
When this happen, there will be lesser people who use the substitute product. in the end, the demand for the milk tea will fall.
That would be the market performance of an investment.
