In a difference of proportion test with alpha = .05, the critical values(s) for a two-tailed test is/are -2.575 and 2.575 1.96 -1.645 and 1.645 -1.96 and 1.96 If the test statistic for a difference of means test has a p-value of .065, we could reject the Null Hypothesis at an alpha level of.10. True False

A 0.01 significance level is used for a hypothesis test of the claim that when parents use a particular method of gender selection, the proportion of baby girls is less less than 0.5. Assume that sample data consists of 45 girls in 100 births, so the sample statistic of StartFraction 9 Over 20 EndFraction 9 20 results in a z score that is 1 standard deviation below below 0.
