10. The null and alternative hypotheses

For each pair of hypotheses that follows, decide whether H₀ and H₁ are set up correctly as the null and alternative hypotheses for a hypothesis test. If so, select “Valid” from the drop down menu. If not, select “Invalid”.
1 H₀: M = 145   2 H₀: μ = 19  
  H₁: M ≠ 145        H₁: μ ≠ 19     
 
3 H₀: μ = 324   4 H₀: µ = 59  
  H₁: μ ≠ 324        H₁: µ ≠ 66     
 
You evaluate the    by assuming that it is true and testing the reasonableness of this assumption by calculating the probability of getting the results if chance alone is operating.
