Consider the following. (Give your answers correct to two decimal places.) (a) Calculate the value for the test statistic, ? 2 , for H o : ? 2 = 18, n = 19, s 2 = 16.4. ? 2 * = (b) Calculate the value...

(a) Calculate the value for the test statistic, ?², forH
_o: ?² = 18,n = 19,s
² = 16.4.
?²* =


(b) Calculate the value for the test statistic, ?², forH
_o: ?² = 28.3,n = 27,s = 5.9.
?²* =


(c) Calculate the value for the test statistic, ?², forH
_o: ? = 42.5,n = 25,s = 39.1.
?²* =


(d) Calculate the value for the test statistic, ?², forH
_o: ? = 11.7,n = 17,s
² = 172.
?²* =
