the mean final examination scores for students taking SM2703 is 30 marks (out f 50 marks) with standard deviation of 6 marks. Assume that the final scores are approximately normal. Two random samples were taken randomly consisting of 32 and 50 students respectively. What is the probability that: a) The mean final examination scores will differ by more than 3 marks? b) Mean final examination scores from group 1 is larger than group 2? vv

Part 1: Suppose the mean score on the first exam is a 60 out of 100. I would like to curve the exam to force the mean score to be an 80 out of 100. If I added 20 to everyone’s score, would the SD of the exam scores change? How about if I multiplied 4/3 to everyone’s score? Explain. Part 2: Continuing from Part 1, fill out the formulas put below that will always be true. Let a =...

A firm with annual sales of $60 million pays out 50% of its sales as cost of goods sold. Overhead amounts to $10 million. Labour and salaries are $14 million. Thus, a profit of $6 million is realised. Assets are $20 million, of which 20% are in inventories. a) If the firm can (1) increase sales volume, (2) raise price, (3) reduce labour and salaries, (4) decrease overhead, or (5) reduce the costs of goods sold, how much change (in...
