The file P13_22.xlsx contains total monthly U.S. retail sales data. While holding out the final six months of observations for validation purposes, use the method of moving averages with a carefully chosen span to forecast U.S. retail sales in the next year. Comment on the performance of your model. What makes this time series more challenging to forecast?

What are measurement scales, their types. Explain each in detail with proper explanation and examples. The sales tax officer in a district has reported that the average sales of the 50 business firms that dealt with during last year amounted to Rs. 36,000 /-with a standard deviatonof Rs10,000 / -. Assuming that the sales of these firms were normally distributed find: (For z-values, use the z table from internet) (a) The no. of business firms the sales of which were over Rs. 40,000 /- (b) The % of business firms the sales of which were likely to range between Rs. 30,000 and Rs40,000

4. ABC Dog Food Company located in Ottawa sells large bags of dog food to warehouse clubs. ABC uses an automatic filling process to fill the bags. Weights of the filled bags are approximately normally distributed with a mean of 50 kilograms and a standard deviation of 1.25 kilograms. (a) What is the probability that a filled bag will weigh less than 49.5 kilograms? (b) What is the probability that a randomly sampled filled bag will weigh between 48.5 and 51 kilograms? (c) What is the minimum weight a bag of dog food could be and remain in the top 15% of all bags filled? (d) ABC is unable to adjust the mean of the filling process. However, it is able to adjust the standard deviation of the filling process. What would the standard deviation need to be so that 2% of all filled bags weigh more than 52 kilograms?
