We reject the null hypothesis, H

= 150, against the alternative hypothesis,

: μ > 150. The test t value is t

= 5.656854, with a P-value =

0.000000393525. The critical value of t is t

= 1.676551, corresponding to a

critical ⎯x = 152.371.

Press @GRAPH to see the results graphically as follows:

– Data from two samples show that⎯x

= 4.5, n1 = 50, and n

= 55. For α = 0.05, and a “pooled” variance, test

the hypothesis H

= 0, against the alternative hypothesis, H
