Perform the following hypothesis test of a proportion: HO: p = 0.33 HA: p not equal to 0.33 The sample proportion is 0.31 based on a sample size of 100. Use a 10% significance level. A) What is the value of the test statistic? (Give answer rounded to 2 decimals) (be careful to make sure your + or - sign is correct) B) What is the p-value for the problem? C) should the null hypothesis be rejected? YES or NO

5 In a hypothesis test for a proportion, the null hypothesis is HO: p = 0.7 and the alternative hypothesis is H1: P = 0.7 with a = 0.05. Then we reject HO if the test statistic Z is 15 (5 Points) between -1.64 and 1.64 and cannot reject H0 otherwise greater than 1.64 or less than-1.64 and cannot reject H0 otherwise between -1.96 and 1.96 and cannot reject HO otherwise greater than 1.96 or less than-1.96 and cannot reject...

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...
