Select ∝ ≠ 150. Then, press @@@OK@@@. The result is:

Then, we reject H0: = 150, against H1: ∝ ≠ 150. The test z value is z0 = 5.656854. The P-value is 1.5410-8. The critical values of ±zα/2 =

±1.959964, corresponding to critical x range of {147.2 152.8}.

This information can be observed graphically by pressing the soft-menu key @GRAPH:
