Interpret the model estimates for age and gender. A cross-sectional study examined the association between the quality of physical health (dependent variable;quantitative, measured on a scale of 0-100) and several hypothesized factors.

In a study on speed control, it was found that the main reasons for regulations were to make traffic flow more efficient and to minimize the risk of danger. An area that was focused on in the study was the distance required to completely stop a vehicle at various speeds. Use the following table to answer the questions. МPH Braking distance (feet) 20 20 30 45 40 81 50 133 60 205 80 411 Assume MPH is going to be used to predict stopping distance. Which of the two variables is the independent variable? Which is the dependent variable? What type of variable is the independent variable? What type of variable is the independent variable? Is there a linear relationship between the two variables?

The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states. I 11.7 8 6.8 3.6 2.3 2.5 2.5 0.4 y 13.7 11 9.8 I= thousands of automatic weapons 7.4 6.2 6.2 4.2 y = murders per 100,000 residents This data can be modeled by the equation y = 0.84x + 4.11. Use this equation to answer the following; Special Note: I suggest you verify this equation by performing linear regression on your calculator. Use the equation with the values rounded to two decimal places to make your predictions. A) How many murders per 100,000 residents can be expected in a state with 8.5 thousand automatic weapons? Answer = Round to 3 decimal places. B) How many murders per 100,000 residents can be expected in a state with 2.8 thousand automatic weapons? Answer Round to 3 decimal places.

Prehistoric pottery vessels are usually found as sherds (broken pieces) and are carefully reconstructed if enough sherds can be found. Information taken from Mimbres Mogollon Archaeology by A. I. Woosley and A. J. McIntyre (University of New Mexico Press) provides data relating x = body diameter in centimeters and y = height in centimeters of prehistoric vessels reconstructed from sherds found at a prehistoric site. The following Minitab printout provides an analysis of the data.

Joan's Nursery specializes in custom-designed landscaping for residential areas. The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost estimating purposes, managers use two hours of labor time for the planting of a medium-sized tree. Actual times from a sample of 10 plantings during the past month follow (times in 2 hours). 3.2 1.5 1.7 2.5 3.0 2.5 2.3 1.8 3.7 2.7 With a 0.05 level of significance, test to see whether the mean tree-planting time differs from two b.
