How do I solve this If the sample standard deviation??

Posted on 2014-12-06 06:25:00 in Math by HYEL

Totest H_0:standard deviation =1.1 versus H_1 : standard deviation doesn’t equal 1.1, a random sample of size n=17 is obtained from a population that is known to be normally distributed

(a) Ifthe sample standard deviation is determined to be s= 2.4, compute the test statistic
chi^2_0= (round to 3 decimal places as needed)
My answer is 76.165

(b)If the researcher decides to test this hypothesis at the a= .10 level of significance, determine the critical values
The critical values are chi^2_.05= __ and chi^2_.95=__ (round to 3 decimal places)
My answers are 26.296 and 7.962

(c) will the researcher reject the null hypothesis? Why? (I chose b)

a) yes because the test statistic is in the critical region

b) no because the test statistic is not in the critical region

c) yes because the test statistic is not in the critical region

d) no because the test statistic is in the critical region
