! Required information To assess the effect of piston ring type and oil type on piston ring wear, three types of piston rings and four types of oil were studied. Three replications of an experiment, in which the number of milligrams of material lost from the ring in four hours of running was measured, were carried out for each of the 12 combinations of oil type and piston ring type. With oil type as the row effect and piston ring type as the column effect, the following sums of squares were observed: SSA 1.293, SSB = 0.9340, SSAB = 0.2485, SSE 1.7034. Is it plausible that the main effects of oil type are all equal to O? Provide the value of the test statistic and the P-value. (Round th answer to three decimal places.)

Urban Travel Times Population of cities and driving times are related, as shown in the accompanying table, which shows the 1960 population N, in thousands, for several cities, together with the average time T, in minutes, sent by residents driving to work. City Population N Driving time T Los Angeles 6489 16.8 Pittsburgh 1804 12.6 Washington 1808 14.3 Hutchinson 38 6.1 Nashville 347 10.8 Tallahassee 48 7.3 An analysis of these data, along with data from 17 other cities in the United States and Canada, led to a power model of average driving time as a function of population. a Construct a power model of driving time in minutes as a function of population measured in thousands b Is average driving time in Pittsburgh more or less than would be expected from its population? c If you wish to move to a smaller city to reduce your average driving time to work by 25, how much smaller should the city be?

Engineers aim to analyze the impact of polypropylene fibers on the compressive strength of concrete. They create 15 concrete cubes and allocate them randomly across five levels of fiber content (0%, 0.25%, 0.50%, 0.75%, and 1%), then measure the concrete strength. The resulting data are as follows Fiber contents in % Obs 0 1 2 3 4 5 7.80 7.40 7.20 7.90 7.30 0.5 1 7.40 5.70 6.90 5.80 7.10 5.60 7.00 5.50 7.20 5.30 What is the ratio of MS trmt and MSE, that is, MS trmt/MSE?

A college professor is interested in exam performance and sleep habits of her students. She collected data for six months and the results are in the following table.
A study was carried out to compare the writing lifetimes of four premium brands of pens (factor A). It was thought that the writing surface (factor B) might affect lifetime, so three different surfaces were randomly selected. A writing machine was used to ensure that conditions were otherwise homogeneous (e.g., constant pressure and a fixed angle). The accompanying table shows the two lifetimes (min) obtained for each brand-surface combination.

A medical student at a community college in city Q wants to study the factors affecting the systolic blood pressure of a person (Y). Generally, the systolic blood pressure depends on the BMI of a person (B) and the age of the person A. She wants to test whether or not the BMI has a significant effect on the systolic blood pressure, keeping the age of the person constant. For her study, she collects a random sample of 150 patients from the city and estimates the following regression function: Y= 15.50 +0.90B + 1.10A. (0.48) (0.35) The test statistic of the study the student wants to conduct (Ho: B, =0 vs. H4: B, #0), keeping other variables constant is. (Round your answer to two decimal places.) At the 5% significance level, the student will v the null hypothesis. Keeping BMI constant, she now wants test whether the age of a person (A) has no significant effect or a positive effect on the person's systolic blood pressure.

A study was conducted to examine the effect of diet cola consumption on calcium levels in women. A sample of 16 healthy women aged 18 to 40 were randomly assigned to drink 24 ounces of either diet cola or water. Their urine was collected for three hours after ingestion of the beverage and calcium excretion (in mg) was measured. The data are stored in ColaCalcium.
