In testing the null hypothesis H₀: μ1 - μ2 = 0, the computed test statistic is z = -1.66. The corresponding p-value is _____. A) .0485 B) .0970 C) .9515 D) .9030

Question

The p-value for a two-tailed test is found by doubling the area in the tail beyond the observed test statistic. Since the z-score is -1.66, we look up the area in the standard normal distribution table or use a calculator to find the area to the left of -1.66, which is approximately 0.0485. Doubling this gives us 0.0970, which corresponds to choice B.
