The discussion revolves around calculating the number of six-letter words formed from four different consonants and two different vowels using the English alphabet. Participants question whether letter repetition is allowed and if nonsensical combinations, like "cdvowu," are acceptable. Clarification is sought on whether the inquiry pertains to all possible combinations or specific chosen letters. One contributor expresses concern that another user has posted multiple assignments without attempting to solve them first. The conversation emphasizes the importance of demonstrating thought processes in problem-solving.

Thread 'Hypothesis testing: Defining H0, HA hypotheses so that ( H_A)_A' makes sense'

The standard _A " operator" maps a Null Hypothesis Ho into a decision set { Do not reject:=1 and reject :=0}. In this sense ( HA)_A , makes no sense. Since H0, HA aren't exhaustive, can we find an alternative operator, _A' , so that ( H_A)_A' makes sense? Isn't Pearson Neyman related to this? Hope I'm making sense. Edit: I was motivated by a superficial similarity of the idea with double transposition of matrices M, with ## (M^{T})^{T}=M##, and just wanted to see if it made sense to talk...
