Question
To test H 0 : = 1.2 versus H 1 : 1.2, a random sample of size n = 22 is obtained from a population
To test H0: = 1.2 versus H1: 1.2, a random sample of size n = 22 is obtained from a population that is known to be normally distributed.
a.If sample standard deviation is 0.8, compute the test statistic.
b.If the researcher decides to test this hypothesis at the 0.1 level of significance, determine the critical value.
c.Draw a chi-square distribution and depict the critical values.
d.Will the researcher reject the null hypothesis? Why?To test H0: = 1.2 versus H1: 1.2, a random sample of size n = 22 is obtained from a population that is known to be normally distributed.
