When you perform a hypothesis test in Minitab, you can choose to display an individual value plot, a boxplot, and a histogram with your results. These and other graphs can help you summarize your results and more fully interpret the statistical results of a hypothesis test.

A mosquito coil is a mosquito-repelling incense, usually made into spiral, and typically made using dried paste of pyrethrum powder. Since, we don’t have pyrethrum powder, first thing that comes into our mind is to use a cheaper and natural mosquito coil.(Wikipedia, n.d.) Mosquito coils keep annoying bugs away-but there might be a trade ...

regressions for two insecticides by a parallelism test (Annex 1). Results of two series of assays are considered as not significantly different if slopes of their log-probit lines are identical (i.e. null hypothesis of the parallelism test is not rejected) and the confidence intervals of their LC50 or LD50 overlap. 2.2 Diagnostic concentration

The null hypothesis The null hypothesis is that the lady has no ability to taste the di erence. If so, all possible ways of lining up the lady’s judgements and the truth about the tea cups should be equally likely. Equally likely because of the random order of presentation. The test statistic is the number of correct judgements.

a. A significance test for comparing two means gave t=−1.97 with 10 degrees of freedom. Can you reject the null hypothesis that the μ’s are equal versus the two-sided alternative at the 5% significance level? Answer: Probability for t = -1.97 for df = 10 is between 0.025 and 0.05. So for two-sided test, the p- value is between 0.05 and 0.1.
