Blockbusting is grabbing the land of the real owners by deceiving them in terms like saying them that the surrounding land will be owned by uncivilized black people (a tastic used in some 1900s), religions that are threat to your coming offsprings and stuffs like that to emotionally force the white owner to sell their property at below fair value. Then later the land was sold to other customers at above fair value due to provision of facilities that were rare in those days.
Answer:
A) The use of both techniques ( i.e. questionnaire and Interview )
B) The sampling method should include an equal number of workers from each shift, this is to ensure that every shift's opinion is broadly covered.
Explanation:
A) The best approach in resolving this problem is the application of both questionnaires and interviews, this is because the questions will be covered in both the questionnaire and interview therefore a more detailed/accurate answer can be gotten by combining both processes
B) The sampling method should include an equal number of workers from each shift, this is to ensure that every shift's opinion is broadly covered.
A single unit or equal part of stock is a Corporation .
B. Has a large amount of savings and wants to make an investment
Answer:
0.4998
Explanation:
Given that:
Mean life of computer μ = 80
standard deviation σ = 8
Mean of sample n = 73
x = 83.28
We have to find P(Mean of sample is less than 83.38 months) =
P(X<x=83.38), to do this we have to first determine the z score.
Since we are dealing with multiple samples, the z score will :
z = (x – μ) / (σ / √n)
z = (83.28 - 80)/ (8/√73)
z = 3.28/0.936
z = 3.5
P(X<x=83.38) = P ( Z < z = 3.5)
Use the standard normal table to find P ( Z < 3.5 )
We will have P (Z < 3.5 ) = 0.4998
The probability that the mean of a sample of 73 computers would be less than 83.28 months is 0.4998
