I need the answer as soon as possible Q3: An investigator has reported the data tabulated below for an experiment todetermine the growth rate of bacteria k (per d), as a function of oxygenconcentration c (mg/L). It is known that such data can be modeled by thefollowing equation:11Cs1kkmaxkmax c2where cs and kmax are parameters. Use linear regression to estimate c, and kmaxand predict the growth rate at c =2 mg/L.0.50.81.52.5k1.12.45.37.68.9Note:y = ao + a1.xykao =kmaxCsa =kmax1x =c2

The linear equation is represented as y=a+bx. The least square regression technique is used to…

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?
