... 9. One-Tailed Hypothesis Test - Evaluation of a conjecture for which sample results that are only sufficiently less than or greater than the conjectured value of the parameter will result in rejection of the null hypothesis, i.e., for a null hypothesis that includes an inequality between the conjec ...

... interval would be 138.8 9.65x1.96 m, or 138.8 18.91 m. In other words, if we were to repeat this experiment over and over again then in 95% of cases the mean could be expected to fall within the range of values 119.89 to 157.71. These limiting values are the confidence limits. But our sample was n ...

... The distribution of the number of pizzas consumed by each UCLA student in their freshman year is very right skewed. One UCLA residential coordinator claims the mean is 7 pizzas per year. The first three parts are True/False. (a) If we take a sample of 100 students and plot the number of pizzas they ...

Tests in the normal distribution
... If we know in advance that sample no.2 always results in larger measurement results than sample no.1, a One-sided test is employed: Critical values are found to be 2.015 respectively (5% level) and 3.365 (1% level). The conclusion is here the same as for a two-tailed test. Test no. 6 – test of a g ...

There are 2 types of confidence intervals for the unknown mean, µ
... There are 2 types of confidence intervals for the unknown mean, µ, of a single population. The first requires that the population standard deviation, σ, is already known (or at least bounded by a known constant); the latter confidence interval does not require that we know σ, rather, the the sample ...
