Answer:
Answer for the question:
The EAI data has information on the annual incomes of managers and whether they have attended the training program or not. This data comprise all the 2500 managers that work for this organization. Using this information, address the following questions: Select a simple random sample of 150 managers and another of 250 managers and calculate the point estimates for the population mean, standard deviation, and proportion. How do the results you obtained for n = 150 and n = 250 compare to the population information? Provide a descriptive assessment of the incomes of those managers with training and those without training. Is your assessment in line with the population information? Referring to c), what do you need to do to be able to make a definitive conclusion of the relationship between training and the mean salary of the managers?

Answer:
Step-by-step explanation:
Area of the triangle
A = b*h/2
b = 18
h = 15
Area = 18*15/2
Area = 135
Area of Parallelogram
A = b * h
b = 18
h = 15
Area = 18 * 15
Area = 270
Note: The parallelogram = 2 * Area of Triangle.
Answer:
1.63% probability that the 10 selected include include all the best 5 engineers in the group of 20
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the engineers are selected is not important, so the combinations formula is used to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
10 engineers selected from a set of 20.
5 best, from a set of 5.
Other 5, from a set of 20-5 = 15.
Totao outcomes:
10 engineers selected from a set of 20.
Probability:
1.63% probability that the 10 selected include include all the best 5 engineers in the group of 20
Answer: No. To the contrary, "12,000,000" is the "standard form" of
"1.2 times 10 to the POSITIVE 7 power.
That is; "12,000,000 = 1.2 * 10⁷ " .
