Question:

Use the data in Exercise 26 in Section 13.1 for the following.

a. Compute a point estimate for the mean evaporation rate when the temperature is 20°C.

b. Construct a 99% confidence interval for the mean evaporation rate for all days with a temperature of 20°C.

c. Predict the evaporation rate when the temperature is 20°C.

d. Construct a 99% prediction interval for the evaporation rate on a given day with a temperature of 20°C.

Exercise 26

In a study to determine the relationship between ambient outdoor temperature and the rate of evaporation of water from soil, measurements of average daytime temperature in °C and evaporation in millimeters per day were taken for 10 days. The results are shown in the following table.image text in transcribed
