第五题 为什么 fcff 在t=o的时候不计入呢 因为定义是forecasted future cf 么 所以o时刻的就算有也不计入？

Investor believes that the mean price of houses in the area is greater than $135,000. A random sample of 25 houses in the area has a mean price of $139,750. The population standard deviation is $24,000. At a 1% level of significance, we should: A Reject the null hypothesis. B Fail to reject the null hypothesis. C Neither rejects nor fails to reject the null hypothesis. 这题答案是否错误？1%对应的应该是2.58吧？

老师你好，针对这个题目中的自由度和ANOVA表格中的自由度有什么区别呢？还是说这里面的自由度是针对t test来说的？

Which of the following statements about hypothesis testing is least accurate? A A type I error is to reject the null when it is actually true. B The significance level equals the probability of a Type I error. C A two-tailed test with a significance level of 5% has z-critical values of ±1.65. b有点不明吧，significance level 指的是两边的区域吧，可以定义为type1吗？

请问，图中statement2，nominal改成real就是对的么
