Answer Null hypothesis H0: = 24 hours Alternative hypothesis: H1: ≠ 24 hours Df = 7 Critical t value = ±2.36 Sample Mean = 25 Standard deviation = 1.195 The test statistic used is P-value = 0.049867231 Since calculated p-value 0.049867231 is slightly less than 0.05(significance level) therefore we reject the null hypothesis

edition of Complete Business Statistics‚ we focus on many improvements in the text‚ driven largely by recommendations from dedicated users and others who teach business statistics. In their reviews‚ these professors suggested ways to improve the book by maintaining the Excel feature while incorporating MINITAB‚ as well as by adding new content and pedagogy‚ and by updating the source material. Additionally‚ there is increased emphasis on good applications of statistics‚ and a wealth of excellent

model. We show that the Joint asymptotic distribution of these test statistics and the test statistics from the hypothesis test H: RP = I versus K: R/3 2 r is a weighted sum of two sets of independent X’-distributions. We also derive a useful duality relation between the multivariate inequality constraints test developed here and the multivariate one-sided hypothesis test. In small samples‚ these three test statistics satisfy inequalities similar to those derived by Berndt and Savin (1977)

steps taken which include; state the hypothesis‚ select level of significance for it‚ identify the test statistics‚ formulate decision rule‚ and take a sample to arrive at a decision. On the contrary‚ however‚ McClave‚ 2011 states that there are seven steps including; null hypothesis‚ alternate hypothesis‚ test statistic‚ rejection region‚ assumptions‚ experiment and calculation of test statistic‚

STATISTICS CHAPTER 1 NOTES DATA: consists of information coming from observations‚ counts‚ measurements‚ or responses. STATISTICS: is the science of collecting‚ organizing‚ analyzing‚ and interpreting data in order to make decisions. DATA SETS: -POPULATION: is the collection of all outcomes‚ responses‚ measurements or counts that are of interest -SAMPLE: is a subset or part of a population EXAMPLE OF POPULATION: The age of each resident in an apartment building EXAMPLE OF SAMPLE:

analyse both the testing methods and how each test is conducted. SPSS was used to conduct both the correlation and difference tests and the tables and graphs that are used are also from this programme. Wagner (2007) says that using SPSS for social statistics and research methods indicates the many elements of the programme and how to use it successfully. Correlation Test Correlation is a key part of statistical data and is used to describe the degree of relationship between two variables. This includes

this tells you much more information than just having the average score. If on the other hand the standard deviation is 20 and the average is still 80‚ this tells yet another story. 2. Why would you use a Nonparametric statistic? You would use a Nonparametric statistic to measure something that cannot be measured with numbers. An example would be a movie review that is ranked by stars. You would use this if the data has ranking information but no numerical interpretation. This is also good
