Answer #1
  • The probability of committing a type I error(rejecting the null hypothesis when it is actually true) is called α (alpha) the other name for this is the level of statistical significance.
  • The probability of making a type II error (failing to reject the null hypothesis when it is actually false) is called β (beta).
  • Sample size used is denoted by ,"n,"
  1. As sample size increases, the type 1 error alpha increases &vice versa
  2. as sample size increases, the type 2 error beta decreases ,& vice versa
  3. As type 1 increases ,the type 2 error decreases & vice veesa.

The residues that interact at the interface of the γ-subunit and the α/β protomers of ATP synthase are overwhelmingly hydrophobic. Describe the relationship between these subunits and how they interact during ATP synthesis and explain the benefit of having this large degree of hydrophobicity. (Think of how hydrophobic substances you know of feel).
