treatment

subject

response variable

all of the above.

2

In a randomized block design, which of the following is true?

the subject to the treatments within each block is randomized

equal variance assumption is violated

normal population assumption is violated.

3

The actual closing daily stock price of a corporation for December 9 is $81.37. Suppose the forecast price for December 9 is $81.88. Using an exponential smoothing constant of 0.2 ( = 0.2), what is the forecast stock price for December 10?

81.86

81.55

81.81

81.78.

Solution

1) Defining the experimental design consists of the following steps:

1. Identify the experimental unit.

2. Identify the types of variables.

3. Define the treatment structure.

4. Define the design structure.

Answer is all of above

2)

In a randomized block design,the subject to the treatments within each block is randomized

3) Forecast for december 10 = 0.2 * 81.37 + 0.8 * 81.88

= 81.78

Answer is 81.78
