Mariah Jacobsen is the marketing manager at ABC Electronics, a major consumer electronics supplier in the northwest. Over the last five years, sales of the company's flagship product - the Wizer Anonymizer (the WA) - have been 45000, 45500, 44500, 46000 and 44000 units. This rate of sales is considered average for the product over the last twenty years or so. Ms. Jacobsen believes that the distribution of the WA's sales is normal with a standard deviation of 1500 units. If she were asked to make a forecast of next year's sales to upper management, what is the likelihood that she would be correct if she predicts sales between 43000 and 46000?

The table shows the total number of trade apprenticeships in Canada each year from 1991 to 1997 a) Consider the year 1991 as year #0. Create a scatter plot of the data on the next page using the DESMOS graphing calculator. apprenticeships 192,945 Year 1991 1992 180,965 168,985 163,750 163,370 1993 1994 1995 1996 165,325 171,180 1997 b) From the scatter plot, which model appears most appropriate: linear, quadratic, exponential. Give reason for your answer c) Generate a model for the data (line/curve of best fit) using regression. Write the equation of the model that best fits the data. d) Use the model to predict when apprenticeships will return to 1991 levels.
Determine if the data are approximately normally distributed. Please use R software.
