Answer:

The best prediction is that 45 people will like the clothing store the best.

Step-by-step explanation:

The total amount of people starts at 50. It then increases to 125. To get to 125, 50 must have been multiplied by 2.5. Therefore, we will also multiply the number of people who favor the clothing store, 18, by 2.5. 18 x 2.5 = 45.

 (6 pts) The average age of CEOs is 56 years. Assume the variable is normally distributed. If the SD is four years, find the pr

Alenkinab [10]

Answer:

The probability that the age of a randomly selected CEO will be between 50 and 55 years old is 0.334.

Step-by-step explanation:

We have a normal distribution with mean=56 years and s.d.=4 years.

We have to calculate the probability that a randomly selected CEO have an age between 50 and 55.

We have to calculate the z-value for 50 and 55.

For x=50:

$z=\frac{x-\mu}{\sigma}=\frac{50-56}{4}=\frac{-6}{4}= -1.5$

For x=55:

$z=\frac{x-\mu}{\sigma}=\frac{55-56}{4}=\frac{-1}{4}=-0.25$

The probability of being between 50 and 55 years is equal to the difference between the probability of being under 55 years and the probability of being under 50 years:

With respect to conducting a situation analysis, what does the phrase "Analysis alone is not a solution" mean?

nikklg [1K]

Answer: Analysis alone is not sufficient because a relationship should be made between a persons instinct and his judgement of matters to arrive at a useful conclusion.

Step-by-step explanation:

While it is necessary to conduct a situation analysis, it is also important to note that a situation analysis on its own is not enough because there should be a relationship drawn between good judgment and instinct so as to make the outcome of the analysis relevant when making important decisions.

For a situation analysis to be effective, information must be broken down sufficiently into bits so as to have a proper understanding as to why organizations, customers, and individuals behave or work the way they do. After these things are thoroughly understood, then the decision maker can make a more effective decision.
