1.

Use the year/subway fare data shown below. Let x represent the year, with 1960 coded as 1, 1973 coded as 14, and so on. Let y represent the subway fare. Does the best model appear to be a good model? Why or why not? Using the best model, find the projected subway fare in the year

20102010.

Year	1960	1973	1986	1995	2002	2003
Subway Fare	0.100.10	0.300.30	0.950.95	1.301.30	1.501.50	2.002.00

Does the best model appear to be a good model? Why or why not?

The best model is the ____ which does not appear

to be a good model because its coefficient of determination is R2 equals=

The data show systolic and diastolic blood pressure of certain people. Find the regression equation, letting the first variable be the independent (x) variable. Find the best predicted diastolic pressure for a person with a systolic reading of

113113.

Use a significance level of 0.05.

Let x represent the number of mountain climbers killed each year. The long-term variance of x is approximately σ2 = 136.2. Suppose that for the past 6 years, the variance has been s2 = 116.9. Use a 1% level of significance to test the claim that the recent variance for number of mountain-climber deaths is less than 136.2. Find a 90% confidence interval for the population variance. (a) What is the level of significance? State the null and alternate hypotheses....
