Our goal here is to compare the distance 3 different types of balls will go when thrown from a contraption known as a statapult. An example of the 3 different kinds of balls is shown below, with (from left to right) Foam, Tennis, and an unknown Rubber Composite. Ball Types A statapult is essentially a small catapult, with a measurement system a...

A civil engineer is interested in determining whether four different methods of estimating flood flow frequency produce equivalent estimates of peak discharge when applied to the same watershed. Each procedure is used six times on the watershed, and the resulting discharge data (in cubic feet per second) are shown below. type1 <- c( .34, .12, ...

1. Suppose we wish to design a new experiment that tests for a significant difference between the mean effective life of these 4 insulating fluids at an accelerated load of 35kV. The variance of fluid life is estimated to be 4.5hrs based on preliminary data. We would like this test to have a type 1 error probability of 0.05, and for this test to ...

Question 1 The diameter of a ball bearing was measured by 12 inspectors, each using two different kinds of calipers. The results were: Inspector <- c(1 ,2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) Caliper1 <- c( 0.265,0.265 ,0.266, 0.267 ,0.267, 0.265 ,0.267 ,0.267, 0.265 ,0.268,0.268, 0.265) Caliper2 <- c( 0.264,0.265, 0.264 ...

Question 1 One method for assessing the bioavailability of a drug is to note its concentration in blood and/or urine samples at certain periods of time after the drug is given. Suppose we want to compare the concentrations of two types of aspirin (types A and B) in urine specimens taken from the same person 1 hour after he/ she has taken the drug...

Question 1 Two machines fill bottles to a net volume of 16 oz. The filling process is assumed to be normal, with stdev1 of .015 and stdev2 of .018. The quality department suspects they both fill exactly the same volumes, whether or not it’s actuall 16. An expirement is performed: data <- c(16.03, 16.04 ,16.05, 16.05 ,16.02 ,16.01, 15.96...
