Lobster fishing study. Refer to the Bulletin of Marine Science (April 201 0) study of teams of fishermen fishing for the red spiny lobster in Baja California Sur, Mexico, Exercise 11. 20 (p. 630). A simple linear regression model relating y =total catch of lobsters (in kilograms) and x =average percentage of traps allocated per day to exploring areas of unknown catch (called search frequency) was fit to the data in the file. A portion of the XLSTAT printout is reproduced at the bottom of the page.
a. Give the null and alternative hypotheses for testing whether total catch (y) is negatively linearly related to search frequency (x).
b. Find the p-value of the test on the XLSTAT printout.
c. Give the appropriate conclusion of the test, part c, using α = .05.

- Find the equation of the regression line for the following data set. x 1 2 3 y 0 3 4arrow_forwardOlympic 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?arrow_forwardWhat does the y -intercept on the graph of a logistic equation correspond to for a population modeled by that equation?arrow_forward

The data for boys of average height are given in Table 11.18.

Note that the data is in levels ( not in logs) I interpret the beta of market as Select one: a. the impact of a one unit variation of market on BA returns on average b. the impact of a one unit % chnage in market on the BA returns on average keeping size and value fixed c. the relation between BA returns and market d. the impact of a one percentage variation of market on BA returns on average in percentage e. the impact of a one unit variation in market on the BA returns on average keeping size and value fixedarrow_forward
- This is only one questionarrow_forwardResearchers at a large nutrition and weight management company are trying to build a model to predict a person’s body fat percentage from an array of variables such as body weight, height, and body measurements around the neck, chest, abdomen, hips, biceps, etc. A variables selection method is used to build a regression model. The final model is shown . Question: What percentage of the variation in percent body fat remains unexplained, even after introducing weight and abdomen circumference into the model? Also state interpretation of the slope for weight.arrow_forwardRetail price data for n = 60 hard disk drives were recently reported in a computer magazine. Three variables were recorded for each hard disk drive: y = Retail PRICE (measured in dollars) x1= Microprocessor SPEED (measured in megahertz) (Values in sample range from 10 to 40) x2 = CHIP size (measured in computer processing units) (Values in sample range from 286 to 486) A first-order regression model was fit to the data.
