Sales of floor cleaners at Lavoie's Flooring Co. over the past 13 months are as follows:

A. Using a moving average with three periods, determine the demand for floor cleaners for next February.

Answer: When using a moving average with three periods, we can determine the demand for floor cleaner in the next February is 3.6

B. Using a weighted moving average with three periods, determine the demand for floor cleaners for February.

Use 4, 2, and 1 for the weights of the most recent, second most recent, and third most recent periods, respectively. For example, if you were forecasting the demand for February, November would have a weight of 1, December would  have a weight of 2, and January would have a weight of 4.

Answer:

C. Use a trend analysis to forecast the demand for floor cleaners.

Answer: ?

D. Evaluate and compare the accuracy of each of these methods using at least one of the forecast error measures.

Answer: ?

F. Are all of the models used in parts a - c appropriate to use with the data provided? Why?

Answer: ?

A child psychologist treats four children who are afraid of snakes with a behavioral modification procedure called systematic desensitization. In this procedure, children were slowly introduced to a snake over four treatment sessions. Children rated how fearful they are of the snake before the first session (baseline) and following each treatment session. Higher ratings indicated greater fear. The hypothetical data are listed in the table.

(a) Complete the F-table. (Round your value for F to two decimal places.)

(b) Compute a Bonferroni procedure and interpret the results. (Assume experimentwise alpha equal to 0.05.)

Ratings of fear significantly decreased from Session 1 to Session 4. Ratings of fear also significantly decreased from Session 2 to Session 4.

Ratings of fear significantly decreased from baseline to Session 3. Ratings of fear also significantly decreased from Session 1 to Session 4.     

Ratings of fear significantly decreased from baseline to Session 3. Ratings of fear also significantly decreased from baseline to Session 4.

None of the pairwise comparisons are significant.
Ratings of fear significantly decreased from baseline to Session 4.

1) find the solution t the non-homogenous DE

y''-16y=3e^5x , y(0)=1 , y'(0)=2

2)find the solution to the DE using cauchy-euler method

x²y''+7xy'+9y=0 , y(1)=2 , y'(1)=3

3)find the solution to the DE using Laplace

y''+8y'+16y=0 , y(0)=-1 , y'(0)=8

Find the general solution

1.(1+x²) (d²y/dx²) + x (dy/dx) + ax = 0

2. ρ(dθ/dρ) –2/ρ (dρ/dθ) = 0

3.(dy/dx)² -4x (dy/dx) +6y = 0

4.y(d²y/dx²) + (dy/dx)² = (dy/dx)

5.Solve simultaneously:

A researcher wants to know whether TV time is related to amount of sharing for boys and girls. To test this, the researcher splits 24 boys and 24 girls into even groups to undergo conditions of no TV, 1 hour of TV, 2 hours of TV, and 3 hours of TV, then measures the number of times they shared toys or food with the other children in their group in an hour-long play-time afterwards.

The resulting data is shown below:
