Expert Solution

Hypothesis testing : can be used to determine whether a statement about the value of a population parametershould or should not be rejected.

  • The null hypothesis, denoted by H0 , is a tentative assumption about a population parameter.
  • The alternative hypothesis, denoted by Ha, is the opposite of what is stated in the null hypothesis.
  • The hypothesis testing procedure uses data from a sample to test the two competing statements indicated by H0 and Ha.
