- Use the table of values you made in part 4 of the example to find the limiting value of the average rate of change in velocity.Olympic Pole Vault The graph in Figure 7 indicates that in recent years the winning Olympic men’s pole vault height has fallen below the value predicted by the regression line in Example 2. This might have occurred because when the pole vault was a new event there was much room for improvement in vaulters’ performances, whereas now even the best training can produce only incremental advances. Let’s see whether concentrating on more recent results gives a better predictor of future records. (a) Use the data in Table 2 (page 176) to complete the table of winning pole vault heights shown in the margin. (Note that we are using x=0 to correspond to the year 1972, where this restricted data set begins.) (b) Find the regression line for the data in part ‚(a). (c) Plot the data and the regression line on the same axes. Does the regression line seem to provide a good model for the data? (d) What does the regression line predict as the winning pole vault height for the 2012 Olympics? Compare this predicted value to the actual 2012 winning height of 5.97 m, as described on page 177. Has this new regression line provided a better prediction than the line in Example 2?FInd the length of a normaal and sub normal ata point ob the curve
- Question 3: Interpreting infographics A 23-year-old male university student is given the task in their exercise physiology class to record their heart rate (in beats per minute) while completing three different activities (resting, walking, and running) each day for a month. He uses excel to create box and whisker plots (Figure 4) to compare central tendency and the spread of the data collected. In 200 - 400 words (written in complete sentences but can be presented as a paragraph or separate dot points); Explain and compare the information in Figure 4 by determining and discussing relevant values including median, maximum, minimum and interquartile range for the three activity types. What percentage of recordings at rest (Figure 4) were between 80 – 95 beats per minute? Does the student have a healthy resting heart rate (see Figure 5)? Has the data been presented effectively in Figure 4? Please explain your answer.What statistical test would be most appropriate if you were interested in seeing how religiosity changes in early adulthood?
