1. Here is a list of fifty wind speed measurements (in kilometres per hour) recorded Hourly on a relatively calm weekend.

6 8 10 12 4 4 5 7 7 8 10 5 6 5 6 8 8 8 11 9

7 8 4 4 4 8 10 8 3 4 5 11 9 6 8 10 11 10 5 7

7 8 7 6 6 9 9 7 9 10

a) Calculate the Mean, Median, Mode, Variance and Standard Deviation.

b) Draw a Box and Whisker Plot

and then

2. A variety store manager notices that sales of soft drinks are higher on hotter days, so he assembles data in a table.

Number of Cans Sold	340	335	410	460	450	610	735	780
High Temperature in Degrees Fahrenheit	55	58	64	68	70	75	80	84

a) Determine the correlation coefficient, line of best fit, and classify the type of correlation that exists.

b) Use the model to predict the soft drink sales if the temperature is 95 degrees Fahrenheit?

c) Use the model to predict the temperature if the number of cans sold is 200?
