The row and column intersection in the t-distribution table indicates that the critical t-value is 1.725. Use either the positiveornegative critical value depending on the direction of your t-test. The graphs below illustrate both one-sided tests. Your results are statistically significant if your...

理论上的 2个 Critical Value 是 -1.645 和 1.645 计算Zc Zc = (p_hat - p0) / sqrt( p0 * q0 / n) Zc = (0.68-0.60) / sqrt(0.60 * 0.40 / 250) = 2.581 2.581 > 1.645, 处于阴影区域,可以拒绝此假设! #2种分布,t-students Distribution 和 正态分布 例1,对2个班级中的2个老师进行测试。

What critical value would you use for a 99% confidence interval based on the t(80) distribution? 1. Determine the critical value of t in each of the following circumstances: a. Confidence Interval = 0.90, n = 10 b. Confidence ...
a给显著性水平α=0.05,查询t分布表,得临界值2.11,因为5.47大于2.11,所以拒绝原假设H0,即回归系数显著不为零。即城镇居民年人均可支配收入X对年人均消费性支出Y有显著影响。 For the level of significance α=0.05, inquires the t distribution list, results in marginal value 2.11, because 5.47 is bigger th...
A cross-sectional, clinical study was conducted to determine the critical value for the standard deviation score (SDS) of waist-hip ratio (WHR)/height (Ht), as an age-adjusted measure of body fat distribution, in relation to occurrence of biochemical complications in obese girls. The (WHR/Ht...
H0是假设相同，所以你可以根据已知的distribution去计算相应的statistics并将它和对应风险的critical value...
