The variance in a production process is an important measure of the quality of the process. a large variance often signals an opportunity for improvement in the process by finding ways to reduce the process variance. conduct a statistical test to determine whether there is a significant difference between the variances in the bag weights for the two machines. use a .05 level of significance. click on the datafile logo to reference the data. machine 1 2.95 3.45 3.50 3.75 3.48 3.26 3.33 3.20 3.16 3.20 3.22 3.38 3.90 3.36 3.25 3.28 3.20 3.22 2.98 3.45 3.70 3.34 3.18 3.35 3.12 machine 2 3.22 3.30 3.34 3.28 3.29 3.25 3.30 3.27 3.38 3.34 3.35 3.19 3.35 3.05 3.36 3.28 3.30 3.28 3.30 3.20 3.16 3.33 state the null and alternative hypotheses. 0: 1 2 2 2 a: 1 2 2 2 calculate the value of the test statistic (to 2 decimals). the p-value is what is your conclusion?

The equation of a circle is (x - 3)2 + (y - 7)2 = 25. determine the length of the radius. 4 25 12.5 5 write the standard equation of the circle with center (2, 3) and a diameter of 12. (x - 2)2 + (y - 3)2 = 36 (x + 2)2 + (y + 3)2 = 12 (x - 2)2 + (y - 3)2 = 6 (x - 3)2 + (y - 2)2 = 36 the equation of a circle is (x + 3)2 + (y + 7)2 = 25. where is (3, 4) located in relation to the circle? on the circle in the interior of the circle in the exterior of the circle at the center of the circle
