A national chain of organic grocery stores ishoping to sell at least 1200 boxes of hemp milk per week at each store; itwill reevaluate the marketing plan if there is compelling evidence that thetrue sales figures are lower. To investigate, the chain will collect a weekof sales data from 61 randomly chosen stores. The standard deviation ofsales at each store is 260 boxes per week. a. Specify appropriate null and alternative hypotheses for this setting.
b. If the chain conducts a test with a critical value of 1150, what is the probability of a Type I error?
c. If, in addition, it turns out that the actual mean weekly sales is 1125 boxes, what is the probability of a Type II error?
d. Confirm your answers to parts (b) and (c) using the HT_errors. xlsx workbook.
e. Use the power_curves. xls workbook to sketch the power curve for the test from part (b).
f. Repeat parts (b)-(e) for the same critical value of 1150, but for a sample size of 122. Explain why your answers changed in the way that they did.

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.

What are the coordinates of the point that is 1/3 of the way from a to b? a (2,-3) b (2,6)

The box plots show the average speeds, in miles per hour, for the race cars in two different races. which correctly describes the consistency of the speeds of the cars in the two races?
