Measuring the Effect of Density on Growth of Mung Bean (Vigna radiata) Plants Wylliam Wagoner1 1 Population and Community Ecology‚ Butler University‚ Indianapolis‚ Indiana 46208‚ USA ABSTRACT For this experiment‚ we set out to find if density and time had an effect on growth of mung bean plants. We decided to test evidence of growth by measuring plant biomass. We measured the biomass each week for four weeks of plants grown at different densities. We found that density had an overall effect

This analysis is appropriate for testing the statistical significant between groups of two less-than interval variables (Zikmund‚ et al. 2010). Although this type of analysis does not show how strong the association between variables is‚ relationships are identified and provide a basis for managerial

this suggests a rejection of the null hypothesis‚ meaning that the control and treatment groups are found to be different. 2. State the null hypothesis for the Baird and Sands (2004) study that focuses on the effect of the GI with PMR treatment on patients’ mobility level. Should the null hypothesis be rejected for the difference between the two groups in change in mobility scores over 12 weeks? Provide a rationale for your answer. The null hypothesis is that the mean mobility scores for

EG381: Module 4 Hypothesis Testing Exercise 4.1 Task 1: Solve the following problems: A student of the author surveyed her friends and found that among 20 males‚ 4 smoke and among 30 female friends‚ 6 smoke. Give two reasons why these results should not be used for a hypothesis test of the claim that the proportions of male smokers and female smokers are equal. First‚ the sample is not random‚ it is a convenience sample and therefore cannot be trusted. Second‚ np҄ = x = 4 < 5‚ therefore
