Using the regression equation from the previous problem, what is the reported anxiety when x is 3? What about 0?  

Using Table 1 (in the tables document), calculate the following:  Standard Deviation:  Variance:

Using Table 1 (in the tables document), find the 5 number summary. Which quartiles has the most data? 

When polling, in district A, 498 of 1000 agreed with Amendment A. In district B, 506 of 1000 agreed with Amendment A. Use alpha = 0.05 conduct a confidence interval for the difference of proportions between district A and district B. Use alpha =0.05.

Using the last two problems (table 2 data), interpret both the hypothesis test and confidence interval. What does each demonstrate?

Using the below table on reported anxiety and medication use, determine what the regression equation is and interpret it.  Coefficients Standard Error t Stat P-value Intercept 6.1 2.1 19.1 0.001 X Variable 1 -3.9 1.1 4.5 0.002

(d) Write the quadratic in factored form. 

Which of the following is perhaps Florida’s most heavily studied spring system (with studies dating back the 19th century)?

Springs are highly productive ecosystems because:
