In order to conduct a hypothesis test for the population
proportion, you sample 450 observations that result in 189
successes. (You may find it useful to reference the
appropriate table: z table or t

a) A significance level of = 0.01 is used in testing a researcher's claim that μ > 100 and the sample data give a test statistic of z = 2.03. Determine the rejection region for this test, and then state the decision for such a test. b) A significance level of = 0.05 is used in testing a researcher's claim that μ 100 and the sample data give a test statistic of z = -1.85. Determine the rejection region for...

A 0.1 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 greater than 0.5. Assume that sample data consists of 91 girls in 169 births, so the sample statistic of 7 results in a z score that is 1 standard deviation above 0.
