Ch10.2 Hypothesis Tests for a Population Proportion Z-Test for a population proportion resting Hypotheses Regarding a Population Proportion, p. se the following steps to perform a Z-Test for a Proportion P-Value Approach By Hand Step 3 Compute the test statistic mple 1: The percentage of physicians who are women is 27.9%. In a survey of physicians employed by a large university health system, 45 of 120 randomly selected physicians were women. Use the P-value approach to determine whether there is...
when conducting a hypothesis test on a population proportion, the value of q is defined as p+1. true or false
You conduct a hypothesis test about a population proportion p at a significance level of a = .01 using a random sample of size n = 38. Your test statistic follows a standard normal distribution when the null hypothesis is true as an equality, and its value obtained from the sample is z = -2.75. Use the Distributions tool to help you answer the questions that follow. Select a Distribution Distributions 0 1 2 3 If you perform a lower...
In order to conduct a hypothesis test for the population proportion, you sample 480 observations that result in 264 successes. (You may find it useful to reference the appropriate table: z table or t table) Ho: p0.60; HA:P 0.60 a-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) Test statistic a-2. Find the p-value. O p-value...
Suppose researchers perform a large-sample test of a population proportion where the null hypothesis is that the population proportion is 0.4, and the alternative hypothesis is that the population proportion is greater than 0.4 (one-sided). They obtain a z-statistic of 2 under the null hypothesis. What is the (one-sided) p-value?
In order to conduct a hypothesis test for the population proportion, you sample 400 observations that result in 212 successes. (You may find it useful to reference the appropriate table: z table or t table) H0: p ≥ 0.54; HA: p < 0.54. a-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) H0: p = 0.54;...
A hypothesis test for a population proportion p is given below: Ho: p = 0.25 vs. Ha: p NE 0.25 (NE means not equal) For sample size n=100 and sample proportion p = 0.30, compute the value of the test statistic: 1.67 -1.12 0.04 1.15
