### To test H0=4.3 versus HA=4.3, a random sample of size n=12 is obtai.pdf

• 1. To test H0:=4.3 versus HA:=4.3, a random sample of size n=12 is obtained from a population that is known to be normally distributed. If the sample standard deviation is determined to be s=4.8, compute the test statistic. 13.707 17.307 17.703 13.077 17.370 Question 17 5pts Refer to question 16. If the researcher decides to test this hypothesis at the =0.05 level of significance, determine the critical values.
