Determine the level of significance for a hypothesis test in each of the following populations given the specified standard error and critical values.Hint:Refer to the values given inTable 7.4:

1. ?=100,?M=8,criticalvalues:84.32and115.68

2. ?=100,?M=6,criticalvalue:113.98

3. ?=100,?M=4,criticalvalue:86.8

TABLE 7.4 Critical Values for One- and Two-Tailed Tests at Three Commonly Used Levels of Significance Type of Test Level of Significance (a) One-Tailed Two-Tailed .05 +1.645 or -1.645 + 1.96 .01 +2.33 or -2.33 + 2.58 001 +3.09 or -3.09 + 3.30
