1. 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^=0.64 with n=75 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: ______________________ (Rejct or Do not Reject) H0.

Step 1
64, p = 0.5, and n = 75. Substitute the values: Z = (0.64 - 0.5) / sqrt(0.5 * 0.5 / 75) Calculate: Z = 0.14 / sqrt(0.25 / 75) = 2.40 Show more…

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=0.3 vs Ha : p<0.3 using the sample results p^=0.22 with n=202. 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: Reject or Do not reject

A random sample of 49 measurements from one population had a sample mean of $10,$ with sample standard deviation $3 .$ An independent random sample of 64 measurements from a second population had a sample mean of $12,$ with sample standard deviation $4 .$ Test the claim that the population means are different. Use level of significance 0.01. (a) Check Requirements What distribution does the sample test statistic follow? Explain. (b) State the hypotheses. (c) Compute $\bar{x}_{1}-\bar{x}_{2}$ and the corresponding sample distribution value. (d) Estimate the $P$ -value of the sample test statistic. (e) Conclude the test. (f) Interpret the results.
