Question:

For effective operation of selling activities, sale force in terms of work force is necessary for a business concern. For attaining predetermined objectives, it is imperative that entire work force should be in place. Work force i.e. in this case salesforce is one of the most precious resources of a business unit. It takes many years to build-up and to develop itself for efficient and effective working.

In a group consist of five (5) students; you are required to do a report on sales force training as the basis of a case study. Discuss the sales force and its training, and development processes to achieve the objectives and good results in a business unit. Explain the methods of improving the productivity of sales force.

Ideally, your report will contain:

1. Table of content

2. Introduction

3. Sales force training and development

4. Methods of improving sales-force productivity

5. Conclusion

6. References

3. The table below shows the results of a survey to determine the lifespans of 200 bulbs taken at random from a factory. Number of bulbs Lifespan (hours) 640 - 659 8 660-659 13 670 - 679 15 680-689 39 690-694 30 695 - 699 43 700 - 704 37 705-714 10 715-734 4 a) Draw a histogram to represent the data. b) State whether this distribution is positively or negatively skewed. (5 marks) (1 mark) c) Determine whether mean or median is more suitable for representing the data. (1 mark) 4. The following table shows the times, to the nearest minutes, spent reading during a particular day by a group of fifty students. Number of children Time (minutes) 10-19 4 20-29 10 30-39 17 40 - 49 9 50 - 59 6 3 60 - 69 70-79 1 a) Construct the cumulative frequency distribution table for this distribution and plot the cumulative frequency curve (ogive). (2 marks) b) Using the cumulative frequency curve, estimate the median and the interquartile range. (9 marks) c) The reading time of one student is wrongly recorded as 26 minutes, while its actual value is 46. State whether this wrong value effects the median and interquartile range. Justify your answer. (Hint: Draw new cumulative frequency curve estimate new median and the interquartile range. (9 marks) 3.
