Running Speed A man is running around a circular track that is 200 m in circumference. An observer uses a stopwatch to record the runner’s time at the each of each lap, obtaining the data in the following table. (a) What was the man’s average speed (rate) between 68 s and 152 s? (b) What was the man’s average speed between 263 s and 412 s? (c) Calculate the man’s speed for cadi lap, Is he slowing down, speeding up, or neither?
Find the indicated z-score shown in the graph to the right. z Area= 0.0571 z=? 0 A normal curve is over a horizontal z-axis and is centered on 0. A vertical line segment extends from the curve to the horizontal axis at a point labeled z = ?. The area under the curve and to the right of the vertical line segment is shaded and labeled Area = 0.0571. The z-score is enter your response here.

1. The height (in feet) and volume of usable lumber (in cubic feet) of 32 cherry trees are measured by a researcher. The goal is to determine if volume of usable lumber can be estimated from the height of a tree. The results are plotted below. (a) The scatterplot suggests A. there is an outlier in the plot.B. there is a positive association between height and volume.C. both A and B.D. neither A nor B.2. Now consider the following scatterplot of the weight of cars (in thousands of pounds) versus their gas mileage (mpg). (a) A plausible value for the correlation between weight and mpg isA. +0.7B. +0.2C. -1.0D. -0.9 Speak
