Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test H0: p = 0.25 vs Ha: p < 0.25 using the sample results p̂p^= 0.13 with sample size n = 100. The standard error of the sample statistic in this situation is 0.043. Round your answer for the test statistic to two decimal places. What is the p-value?...

Answer A and B for first question
A genetic experiment with peas resulted in one sample of offspring that consisted of 447 green peas and 164 yellow peas. a. Construct a 90% confidence interval to estimate of the percentage of yellow peas. b. It was expected that 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not 25%, do the results contradict expectations? a. Construct a 90% confidence interval. Express the percentages...

Current Attempt in Progress Use the normal distribution to find a confidence interval for a difference in proportions p 1 -p 2 given the relevant sample results. Assume the results come from random samples. A 90% confidence interval for p 1 -p 2 given that p^1 = 0.25 with n 1 = 60 and p^2 = 0.40 with n 2 = 80 Give the best estimate for p 1 -p 2, the margin of error, and the confidence interval. Round...

a) Use the t-distribution to find a confidence interval for a difference in means μ1-μ2 given the relevant sample results. Give the best estimate for μ1-μ2, the margin of error, and the confidence interval. Assume the results come from random samples from populations that are approximately normally distributed. A 90% confidence interval for μ1-μ2 using the sample results x¯1=8.8, s1=2.7, n1=50 and x¯2=13.3, s2=6.0, n2=50 Enter the exact answer for the best estimate and round your answers for the margin...

Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test H0 : p=0.75 vs Ha : p≠0.75 using the sample results p^=0.69 with n=118 Round your answer for the test statistic to two decimal places, and your answer for the p-value to three decimal places. test statistic = p-value = Conclusion:

In a program designed to help patients stop smoking, 236 patients were given sustained care, and 84.3% of them were no longer smoking after one month. Use a 0.05 significance level to test the claim that 80% of patients stop smoking when given sustained care. Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho:p*0.8 H: p=0.8 OB. Ho: P = 0.8 H:p<0.8 @ C. Ho: p = 0.8 H:p*0.8 OD. Ho: p=0.8...

SET THREE: Chapter 6, Section 1-HT, Exercise 046 Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test H0 : p=0.5 vs Ha : p>0.5 using the sample results p^=0.60 with n=25 Round your answer for the test statistic to two decimal places, and your answer for the p-value to three decimal places. test statistic = ________________ p-value...

Use the information given below to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). The test statistic in a left-tailed test is z= - 1.29. What is the P-value? P-value = (Round to four decimal places as needed.) p-p Find the value of the test statistic z using z pa n The claim that the proportion of peas with yellow...

For the following information, determine whether a normal sampling distribution can be used, where p is the population proportion, a is the level of significance, p is the sample proportion, and n is the sample size. If it can be used, test the claim. Claim: p20.47; a = 0.06. Sample statistics : P = 0.40, n = 150 Let q=1-p and let = 1-P.
