(All Steps) To test H 0: µ = 4.5 versus H 1 : µ > 4.5, a simple random sample of size n = 13 is obtained from a population that is known to be normally

Question: To test H 0: µ = 4.5 versus H 1 : µ > 4.5, a simple random sample of size n = 13 is obtained from a population that is known to be normally distributed.

  1. If x̃ = 4.9 and s = 1.3, compute the test statistic.
  2. Draw a t -distribution with the area that represents the P -value shaded.
  3. Approximate and interpret the P- value.
  4. If the researcher decides to test this hypothesis at the a = 0.1 level of significance, will the researcher reject the null hypothesis? Why?
