Test H0 : p = 0.75 vs Ha : p ≠ 0.75 using the sample results p^ = 0.69 with n = 120
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:
H0: p ? 0.75 Ha: p < 0.75 A sample of 300 items was selected. Compute the p-value and state your conclusion for each of the following sample results. Use standard deviation = .05. Round your answers to four decimal places. a. = 0.66 p-value is Conclusion: p-value is H0 b. = 0.72 p-value is Conclusion: p-value is H0 c. = 0.7 p-value is Conclusion: p-value is H0 d. = 0.77 p-value is Conclusion: p-value is H0
Suppose we to test H0: η = 4.5 vs. Ha: η< 4.5, where η is the population median. Among n= 10 observations, let S be the number of the measurements which are larger than 4.5. Under H0, S follows a binomial(n= 10,p = 0.5). 1) Which of the following sample results gives the strongest evidence to support Ha? a. S=4 b. S=5 c. S=6 d. They are all the same 2) Following the problem, suppose S = 1, what is...
Consider the following hypothesis test: H: p > 0.75 Ha: p<0.75 A sample of 300 items was selected. Compute the p-value and state your conclusion for each of the following sample results. Use Q=.05.

P = 0.79 Но...
A test of H0: mu = 5 vs Ha: mu =/ 5 Is going to be conducted based on a simple random sample of size 40. Which of the following test stasticics will have the smallest p-value associated with it? Answers: -2.4 -1.8 0.6 2.3 3.7
H0: μ ≤ 16.56 vs. HA: μ > 16.56 What is the test statistic for sample of size 20, mean 11.53, and standard deviation 1.73? Enter the test statistic with 2 decimal places.
Use the t-distribution and the sample results to complete the test of the hypotheses. Use a 5% significance level. Assume the results come from a random sample, and if the sample size is small, assume the underlying distribution is relatively normal. Test H0 : μ=10 vs Ha : μ>10 using the sample results x¯=13.2, s=8.7, with n=12. test statistic = p-value =
Consider the following hypothesis test. H0: p = 0.45 Ha: p ≠ 0.45 A sample of 200 provided a sample proportion p = 0.443. (a) Compute the value of the test statistic. (b) What is the p-value? (c) At α = 0.05, what is your conclusion? (d) What is the rejection rule using the critical value? What is your conclusion?
6. Testing Ho : p = 0.75 versus Ha : p > 0.75 when the sample has n = 20, ˆp = 0.50. (a) Verify that the sample size is large (b) Find the standard error for ˆp (c) Find the value of the standardized z-test statistic
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?...
