Give the hypothesis, critical value and Region, test statistic and conclude A nation-wide real estate chain is in the process of comparing townhouse prices in four citiesacross the country. It is, however, known that the area size of a townhouse is also a determiningfactor on price fixing and should be controlled by using blocks. Therefore, in each city, the sellingprices of a 90m^2, a 120 m^2, a 50^2, a 180m^2 and a 210m^2 townhouse are randomlyselected. The results are recorded to the nearest R1000 and are shown below:TownhouseSize m^290120150180210Bloemfontein660792100412481620Durban74077286010721524Port Elizabeth6927247889161176Johannesburg800784111213281784

A researcher would like to use a factorial study to compare the service provided by two different cell phone companies. Participants will be asked to rate the quality of service provided for phone and internet services. Based on the details provided, identify the 2 factors being examined and the dependent variable.
An agronomist is interested in comparing the efficacy of two fumigants (A and B) and a control (O) in eliminating wireworms. A field is divided into 4 sections, each section containing 3 plots. Fumigant A, B and O were randomly assigned to one plot within each section. The number of wireworms that remained on each plot after application of fumigant was recorded. Give a possible RCBD layout for the experiment.
The structure of a two-factor study can be presented as a matrix with the levels of one factordetermining the rows and the levels of the second factor determining the columns. With thisstructure in mind, describe the mean differences that are evaluated by each of the threehypothesis tests that make up a two-factor ANOVA.
A television network earns an average of $65 million each season from a hit program and loses an average of $25 million each season on a program that turns out to be a flop. Of all programs picked up by this network in recent years, 30% turn out to be hits; the rest turn out to be flops. At a cost of C dollars, a market research firm will analyze a pilot episode of a prospective program and issue a report predicting whether the given program will end up being a hit. If the program is actually going to be a hit, there is a 65% chance that the market researchers will predict the program to be a hit. If the program is actually going to be a flop, there is only a 40% chance that the market researchers will predict the program to be a hit.

In search of a mosquito repellent that is safer than the ones that are currently on the market, scientists have developed a new compound that is rated as less toxic than the current compound, thus making a repellent that contains this new compound safer for human use. Scientists also believe that a repellent containing the new compound will be more effective than the ones that contain the current compound. To test the effectiveness of the new compound versus that of the current compound, scientists have randomly selected 100 people from a state. Up to 100 bins, with an equal number of mosquitoes in each bin, are available for use in the study. After a compound is applied to a participant’s forearm, the participant will insert his or her forearm into a bin for 1 minute, and the number of mosquito bites on the arm at the end of that time will be determined. a. Suppose this study is to be conducted using a completely randomized design. Describe a a.randomization process and identify an…

If you have a sample of 100 patients at a hospital and 20 of them have the flu, what is theprobability of randomly selecting 3 patients in a row who have the flu? You can assume(replacement meaning that when you select a patient a new patient is added to total2number of patient) or not (meaning that after you select a patient the total number ofpatients declines by 1), just be clear about the method you choose.

A study conducted by researchers was designed "to determine if application of duct tape is as effective as cryotherapy in the treatment of common warts." The researchers randomly divided 6969 patients into two groups. The 3535 patients in group 1 had their warts treated by applying duct tape. The 3434 patients in group 2 had their warts treated by cryotherapy. Once the treatments were complete, it was determined that 6969% of the patients in group 1 and 8585% of the patients in group 2 had complete resolution of their warts. The researchers concluded that cryotherapycryotherapy is significantly more effective in treating warts than duct tapeduct tape.

A researcher would like to use a factorial study to compare two programs designed to help people stop smoking. The smoking behavior of each participant will be measured at the beginning of the program, at the end of the program, and again 4 months after the program has ended. Thus, the two treatment program make up one factor, three measurement times make up the second factor. For this study, which factor (s) should be between subjects and which should be within subjects?
