A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: y=a+bx b=-0.66 a=25.376 r²=0.390625 r=-0.625 Use this to predict the number of situps a person who watches 2.5 hours of TV can do. place. Round to one decimal

A fire insurance company wants to relate the amount of fire damage in major residential fires to the distance between the residence and the nearest fire station. The study was conducted in a large suburb of a major city; a sample of fifteen recent fires in the suburb was selected. The amount of damage, y (£000), and the distance, r (km), between the fire and the nearest fire station are given in the following table. 3.4 1.8 4.6 2.3 3.1 5.5 0.7 3.0 y 26.2 17.8 31.3 23.1 27.5 36.0 2.1 y 19.6 31.3 24.0 17.3 43.2 36.4 26.1 14.1 22.3 2.6 4.3 1.1 6.1 4.8 3.8 (a) Fit a simple linear regression model to these data.

K Disk drives have been getting larger. Their capacity is now often given in terabytes (TB) where 1 TB = 1000 gigabytes, or about a trillion bytes. A survey of prices for external disk drives found the data shown to the right. For this data, we want to predict Price from Capacity. Complete parts a through i below. Click the icon to view the disk drive data and summary statistics. Disk Drive Data and Summary Statistics Capacity (in TB) 0.5 1.0 2.0 3.0 4.0 6.0 8.0 12.0 32.0 x = 7.611 SD(x) = 9.85 r = 0.987 --- Print Price (in $) 58.79 75.79 114.00 105.95 146.45 425.49 594.00 1074.00 4464.49 y = 784.329 SD(y) = 1420.27 Done X A. It indicates the price for a hard drive with no capacity. It is meaningless and should not be interpreted. B. It indicates the additional capacity in TB for each additional dollar of price. It is meaningful in that it could be interpreted as the cost of the parts common to all drives.
CURRENT OBJECTIVE Understand and interpret the test-statistic and p-value Question The check-in nurse is concerned about the number of patients coming into the doctor's office with pneumonia. The check-in nurse would like to test the claim that the proportion of patients coming into the doctor's office, who are later diagnosed with pneumonia, is different than 0.10. If the z- test statistic was calculated as z = -1.07, does the check-in nurse have enough evidence to reject the null hypothesis? Assume a = 0.05. Move the blue dot to choose the appropriate test (left-, right, or two-tailed). Then, use the graph below to show the test statistic, p-value, and the rejection region to make a conclusion about the hypothesis test. Move the blue dot to choose the appropriate test Significance level = 0.05 MacBook Pro @ # $ & 3 4 6 7 8 { W E R Y S D F G H J K V B ion command command option .. .. V

A regression was run to determine if there is a relationship between hours of TV watched per day, xx, and number of sit-ups, yy, a person can do in a minute.The results of the regression were: y=ax+b a=-1.399 b=26.311Use this to predict the number of sit-ups a person who watches 12.512.5 hours of TV can do in a minute. Round to the nearest whole number.
