A study was conducted to compare 3 speed reduction marking (SRM) conditions on drivers acceleration in an automobile simulator. A sample of 15 drivers was selected, and each driver drove the simulator under the 3 SRM conditions (No SRM with group mean 0.161, Longitudinal SRM with group mean 0.126, Traverse SRM with group mean -0.032 and overall mean 0.085).

(a) What model design is this?

(b) Create an ANOVA table with degrees of freedom and Sum of Squares (given that SS(Driver)-0.987 and SS(Total)-2.331.

(c)Test whether treatment is significant.

(d) Use Tukeys method to obtain simultaneous 95% confidence intervals for comparing all pairs of treatment means.

(e) Compute the Relative Efficiency for this design relative to the Completely Ran- domized Design, and determine how many drivers per treatment would be needeod for a Completely Randomized Design to have similar standard error of treatment means as this design has.

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
