Question 4

The following table shows information related to the number of salesman and sales made in October 2020 for Jubilee Berhad:

Salesman	Sales
1	200
2	260
3	700
4	840
5	1,000
6	1,100

Required:

Forecast the total sales if the company has 10 salesman.

Determine the correlation coefficient between the number of salesman and total sales if the company maintain the existing number of salesman.

The sales trend can be described by the linear regression equation y = 780 + 4x, where x is the month number (with January 2013 as month 0) and y is sales in RM'000. The average seasonal variation for March is 106%.

Forecast the sales for March 2015 (in thousand RM).

Badrol anticipates that a 90% learning curve will apply to the production of a new item. The first item will cost RM2,500.00 in materials, and will take 500 labour hours. The cost per hour for labour and variable overhead is RM15.00.

Calculate the total cost for the first 8 units.

A manufacturing company has developed a new product. The time taken to manufacture the first unit was 24 minutes. It is expected that an 80% learning curve will apply for the first three months of production.

By the end of that period, the total number of units produced will have reached 1,024. It is then expected that the time taken for each subsequent unit will be the same as the time taken for the 1,024th unit (note that the value of the 80% learning index is -0.3219).

Compute the expected time taken for the 8th unit.
