  1. An experiment is run to determine how well a new process can measure the amountof a certain pesticide in water. The experiment uses the new test and the old test to measure 10 water samples with known amounts. The data below is the number of parts per million that each test differs from for each sample. The old test produces: {30, 19, 24, 24, 24, 13, 22, 12, 19, 33 }

The new test produces: { 29, 25, 29, 29, 27, 29, 27, 32, 32, 24 }

  1. Does the new test produce significantly different results? Use a significance level of 95%.
  2. What are the sample means and deviations of this data?
  3. Give a box-and-whisker plot for each set of data.

We need to know exactly WHAT VARIABLE he measured, and in WHAT UNITS. Newcomb measured the time in seconds that a light signal took to pass from his laboratory on the Potomac River to mirror at the base the Washington Monument an back, a total distance of about 7400 meters.

9. Sum of Squares for the Difference Scores A new form of cognitive therapy has been developed to treat the symptoms of depression. To determine the effectiveness of the treatment, depression scores were measured twice for each person in the sample - once before the therapy began (Pretest) and once after the therapy was completed (Posttest). The values below represent the Beck Depression Inventory scores for the two measurements (higher scores indicate higher levels of depression). Note that each row...

The water quality of a river was investigated by taking 15 water samples and recording the counts of a particular bacteria for each sample, where ???? is the number of bacteria in sample ?? and the ????’s are assumed to be independent and follow a Poisson ( ?oi(?) ) distribution. The data are as follows: {27, 24, 25, 21, 30, 22, 20, 22, 29, 19, 19, 22, 23, 36, 19} 1. Find a point estimate for the population mean number...

Many drivers of cars that can run on regular gas actually buy premium in the belief that they will get better gas mileage. To test that belief, we use 10 cars from a company fleet in which all the cars run on regular gas. Each car is filled first with either regular or premium gasoline, decided by a coin toss, and the mileage for that tankful is recorded. Then the mileage is recorded again for the same car for tankful...

Studies are often done by pharmaceutical companies to determine the effectiveness of a treatment program. Suppose that a new AIDS antibody-drug is currently under study. It is given to patients once the AIDS symptoms have revealed themselves. Of interest is the average length of time in months patients live once starting the treatment. Two researchers each follow a different set of 40 AIDS patients from the start of treatment until their deaths. The following data (in months) are collected\ Researcher...
