Using Appendix C-1 or Appendix C-2 find the p-value for each test statistic. (Round your answers to 4 decimal places.)
| Test Statistic | p-value | ||
| (a) | Right-tailed test | z = +1.80 | |
| (b) | Left-tailed test | z = -2.62 | |

B.
Get the left tailed area of -2.62:
P = 0.0044
C.
Get the left tailed area of -2.32, then multiply by 2:
P = 0.0204
