Power 1 Sample Proportion z-Test (2 Sided)
I work through an example of finding power of a 1 sample proportion z test which is 2 sided. I added some annotations to the language of my examples. Defining the variable: P: The population proportion of people that travel during the holidays. Normality: With 350(.68)=238 and 350(1-.68

We are – almost all of us – deeply attracted to the idea of being normal. But what if our idea of ‘normal’ isn’t normal? A plea for a broader definition of an important term. If you like our films, take a look at our shop (we ship worldwide): https://goo.gl/ojRR53 Join our mailing list: h

Correction: The affiliation of Lei Fu is Tsinghua University. The Grothendieck–Serre conjecture predicts that every generically trivial torsor under a reductive group scheme G over a regular local ring R is trivial. We settle it in the case when G is quasi-split and R is unramified. To ov
