问题如下图:
1.75是查表所得吗?,1.75和均值是什么关系啊。
NO.PZ2020010304000054问题如下Suppose thfor a lineregression, estimation of slope is statehaving a one-sip-value of 0.04. Whes this mean?The p-value tells us the “probability of observing a test statistic this more extreme ththe one computefrom the observeta when the null hypothesis is true.” In other wor, if the estimate of the slope is true, then in a ranmizetrithe probability of getting a larger new slope estimate is 4%.Assuming a normstribution, this will corresponto the value of x thsolves the following equation:1 - Φ(x) = 0.04 Using the excel function NORMSINV gives x = 1.75. 老师,p value和a不都应该是在左边吗?概率累积函数P value左侧的面积才是p value对应的概率呀?

请问这道题是匹配哪个section的知识点啊
