A random sample of n= 22 items is taken, resulting in a sample mean of x = 16.5 with a sample standard deviation of s= 4.1.

Assume x is normally distributed and use = 0.05 and the following hypotheses.

H0: =16

H1:16

Determine the critical value t_c and t score value based on the sample data?

a.

The critical value t_c= 2.0796 The t score value based on the sample data = 0.572

b.

The critical value t_c = 2.0796 The t score value based on the sample data = 0.672

c.

The critical value t_c= 4.0796 The t score value based on the sample data = 0.572

d.

The critical value t_c= 1.0796 The t score value based on the sample data = 0.672
