Putting success How well do professional golfers putt from various distances to the hole? The data show various distances to the hole (in feet) and the percent of putts made at each distance for a sample of golfers.9 Make a scatterplot by hand that shows how the percent of putts made relates to the distance of the putt.

Short Answer

Expert verified

The distance decreases when percent made increases.

Step by step solution

01

Given information

Data for a group of golfers showing the proportion of putts made at various distances from the hole (in feet):

02

Explanation

For scatterplot:

Horizontal axis: Distance (ft.)

Vertical axis: Percent made

Because of the downward slope of the pattern, there is a negative relationship between distance and percent made in the scatterplot.

That implies

The distance decreases when percent made increases.

Scientists examined the activity level of 7 fish at different temperatures. Fish activity was rated on a scale of 0 (no activity) to 100 (maximal activity). The temperature was measured in degrees Celsius. A computer regression printout and a residual plot are provided. Notice that the horizontal axis on the residual plot is labeled 鈥淔itted value,鈥 which means the same thing as 鈥減redicted value.鈥

Which of the following gives a correct interpretation of s in this setting?

a. For every 1掳C increase in temperature, fish activity is predicted to increase by 4.785 units.

b. The typical distance of the temperature readings from their mean is about 4.785掳C.

c. The typical distance of the activity level ratings from the least-squares line is about 4.785 units.

d. The typical distance of the activity level readings from their mean is about 4.785 units.

e. At a temperature of 0掳C, this model predicts an activity level of 4.785 units.

Husbands and wives The mean height of American women in their early twenties is 64.5inches and the standard deviation is 2.5inches. The mean height of men the same age is 68.5inches, with standard deviation2.7inches. The correlation between the heights of husbands and wives is about r=0.5

(a) Find r2and interpret this value in context.

(b) For these data, s=1.2. Explain what this value mean

Joan is concerned about the amount of energy she uses to heat her home.

The scatterplot shows the relationship between x = mean temperature in a particular month

and y = mean amount of natural gas used per day (in cubic feet) in that month, along with the regression line y^=1425鈭19.87x

a. Predict the mean amount of natural gas Joan will use per day in a month with a mean temperature of 30掳F.

b. Predict the mean amount of natural gas Joan will use per day in a month with a mean temperature of 65掳F.

c. How confident are you in each of these predictions? Explain your reasoning.

More long jumps Refer to Exercise 52. Use technology to create a residual plot. Sketch the residual plot and explain what information it provides.

If women always married men who were 2 years older than themselves, what would be the correlation between the ages of husband and wife?

c. 0.5

d. 0
