Question: You will need your text (for tables) and PASW. Save this test as a Word or rtf document and then respond right into the test, including any copying any PASW output into the document.

You wish to be able to predict a swimmer’s 100 m butterfly time from her 50 m butterfly time. Here are the 50 m and 100m butterfly times for 20 competitive female swimmers.

100 m Fly 50 m Fly

57.03 26.09 55.24 26.96 60.03 26.72 56.47 26.64 56.97 25.14 59.73 25.23 56.57 26.68 56.36 28.63 58.39 26.81 55.04 26.68 56.99 26.66 59.12 25.84 54.23 28.43 56.44 26.13 55.44 26.55 56.37 25.21 54.72 25.48 59.29 28.01 59.71 27.74 54.56 27.58

? Have PASW make a scatter plot of this data, with the regression line and bounding lines superimposed. Include the plot in your response.

? Ask PASW to find the correlation between the times.

? Describe and test the hypothesis of meaningful prediction, considering both slope and correlation. Include any appropriate PASW output in your response.

? Predict the 100 m fly times for three competitive female swimmers with 50 m fly times of 26.9, 27.4, and 30.6 respectively.

? Predict the 100 m fly time for a male swimmer with a 50 m fly time of 23.3.

? Discuss the amount of credibility you place in these predictions.
