Hypothesis Testing: Two-Sample Case for the Mean Many cases in the social sciences involve a hypothesis about the difference between two groups (i.e. men and women‚ control and experiment). We analyze statistics from two samples‚ and the hypothesis and confidence interval would deal with the difference between two population means. The following factors are important in hypothesis testing: 1. probability theory 2. the sampling distribution of the statistic 3. the errors inherent

Winter Survival Exercise Situation You have just crash landed somewhere in the woods of southern Manitoba or possibly northern Minnesota. It is 11:32 am in mid-January. The small plane in which you were travelling crashed onto a small lake. The pilot and co-pilot were killed. Shortly after the crash‚ the plane sank completely into the lake with the pilot and co-pilot’s bodies inside. Everyone else on the flight escaped to land dry and without serious injury. The crash came suddenly before the

Chapter Introduction to Microsoft Excel A spreadsheet is a computer program that turns the computer into a very powerful calculator. Headings and comments can be entered along with detailed formulas. The spreadsheet screen is divided into ROWS and COLUMNS; the intersection between a row and a column is termed a CELL. Usually only a small section of the overall spreadsheet is displayed on the screen. 1 The Microsoft Excel Screen 1 Load Microsoft Excel and you should receive the following

Business Statistics‚ 9e (Groebner/Shannon/Fry) Chapter 10 Estimation and Hypothesis Testing for Two Population Parameters 1) The Cranston Hardware Company is interested in estimating the difference in the mean purchase for men customers versus women customers. It wishes to estimate this difference using a 95 percent confidence level. If the sample size is n = 10 from each population‚ the samples are independent‚ and sample standard deviations are used‚ and the variances are assumed equal‚ then

The word ‘Hypothesis is derived from a Greek word‚ which means ‘to suppose’. It is usually considered as the principal instrument in research. For a researcher it is a formal question that he or she intends to resolve. In this way a hypothesis may be defined as a proposition or a supposition. The main function of hypothesis is to guide the collection and processing of materials and direct the research. Hypothesis is a tentative conclusion. It is facts based theory. A research scholar will analyze
