Find the P-value for a left-tailed hypothesis test with a standardized test statistic of z = -1.71. Decide whether to reject H0 when the level of significance is α = 0.05.

a. Use Table 4 in Appendix B to find the area that corresponds to z = -1.71.

b. Calculate the P-value for a left-tailed test, the area in the left tail.

c. Compare the P-value with α and decide whether to reject H0.
