The Edna Manley College’s Filming Department has commissioned a study to determine if the brightness of films produced is impacted by the development technique used. Three film manufacturers were used (Kodak, Polaroid and Fujifilm). Each film was tested based on three developmental techniques (cropping, tonality and colour).
Please use the table(image file) to answer the following questions:
A. Propose the null hypotheses to test whether development technique or film manufacturer have an effect on the brightness of the films produced.
B. Using JASP, please conduct the relevant test to analyze the hypothesis provided. Are there any significant main effects or an interaction effect? Clearly outline all steps.
C. Please provide the JASP output of all the statistical analyses performed as well as the file that was produced.

- What is the answer to question 15?arrow_forwardThe article "Combined Analysis of Real-Time Kinematic GPS Equipment and Its Users for Height Determination" (W. Featherstone and M. Stewart, Journal of Surveying Engineering, 2001:31-51) presents a study of the accuracy of global positioning system (GPS) equipment in measuring heights. Three types of equipment were studied, and each was used to make measurements at four different base stations (in the article a fifth station was included, for which the results differed considerably from the other four). There were 60 measurements made with each piece of equipment at each base. The means and standard deviations of the measurement errors (in mm) are presented in the following table for each combination of equipment type and base station.

Reproducibility Researchers looked at studies that were reported in newspapers with the goal of determining whether initial studies had results that could be reproduced. Reproducibility of results means that subsequent analysis confirms the conclusion of the original study. Primary studies are studies where the researchers come up with a research objective, clearly state the goals of the study and population, describe the research method, test the research hypotheses, and draw conclusions. (a) Among the 156 primary studies reported by newspapers, 76 had results that were validated by subsequent analysis.

A company provides maintenance service for water-filtration systems throughout southern Florida. Customers contact the company with requests for maintenance service on their water-filtration systems. To estimate the service time and the service cost, the company's managers want to predict the repair time necessary for each maintenance request. Hence, repair time in hours is the dependent variable. Repair time is believed to be related to three factors, the number of months since the last maintenance service, the type of repair problem (mechanical or electrical), and the repairperson who performed the service. Data for a sample of 10 service calls are reported in the table below.
