As practiced by many in buying skirts or pants, they use the neckline to check if the waistline of the skirts or pants fits them. We would like to study this claim by using a random sample of neckline and waistline of 15 people. The data collected are summarized as follows: Subject 1 2 3 4 6 7 8 9 10 12 13 14 15 11 Neckline 35 34 38 45 38 33 38 42 44 33 35 31 33 35 30 (cm) Waistline(cm) 83 66 97 100 86 82 77 82 91 62 93 57 67 93 57 3-4. The regression equation is: Waistline'= -3.9964 + 2.30321 neckline 5. Using the regression equation/model for waistline in Number 3-4, estimate the waistline if the neckline of a person is 37 cm. Round off final answer to two decimal places. 6-8. Solve for the coefficient of determination, r2 (Express the answer in percentage form, r2 x 100%; Round off final answers to two decimal places): %3D E(y - 9)? = %3D n2 = 9. Solve for the coefficient of nondetermination (Express the answer in percentage form; Round off final answer to two decimal places):

The income of residents of Chicago, IL has a bell shaped and symmetric histogram, with a mean of $65,000 and a S.D. of $13,000.  1) What percentage of residents have an income more than $78,000 or less than $52,000?   2) what percentage of residents have an income between $39,000 and $91,000?   3) What percentage of residents have an income less than $104,000?  4) What percentage have an income more than $65000?  5)  Less than $26,000 Hint: you need to draw a curve for each part 1-4, and calculate the mean ± 1, 2, 3 S.D.

Another type of painted ceramic vessel is called three-circle red-on-white ( Mimbres Mogollon Archaeology). At four different sites in the Wind Mountain archaeological region, the number of such sherds was counted in local dwelling excavations.
