Question
I am having trouble figuring out how to enter the information for these problems into SPSS in order to run the tests.
High and Low Temperatures March is a month of variable weather in the Northeast. The chart below records the actual high and low temperatures for a selection of days in March from the weather report for Pittsburgh, Pennsylvania. At the 0.01 level of significance, is there sufficient evidence to conclude that there is more than a 10o difference between average highs and lows? (#7, 9-56)

Helpful hint: This assignment requires that you figure out how to group your data before entering it into SPSS. You have "Max and Min" temperatures, and you have numerical values.

Fireworks and Injuries These data were obtained for the years 1993 through 1998 and indicate the number of fireworks (in millions) used and the related injures. Predict the number of injuries if 100 million fireworks are used during a given year (ONLY IF POSSIBLE!). (#28 10-27)

Include a scatter plot. Include the correlation coefficient. Determine the regression line equation (IF IT EXISTS). Plot the regression line on the scatter plot (IF IT EXISTS).

Explanation / Answer
H0: d= mu max - mu min =10
Ha: d = mu max - mu min >10
Right tailed test
Hence reject null hypothesis and accept difference >10
