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 Ho : p = 0.3 vs Ha : p < 0.3 using the sample results p = 0.23 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 = i p-value = i

Please help me with this question.

Need help with just the test statistic and the p-value thank you

Use the data to calculate the sample variance, s. (Round your answer to five decimal places.) n = 7: 1.6, 3.5, 1.6, 2.1, 3.1, 2.9, 3.0 %3D Construct a 95% confidence interval for the population variance, of. (Round your answers to two decimal places.) to Test Ho: = 0.8 versus H: of + 0.8 using a = 0.05. State the test statistic. (Round your answer to two decimal places.) x2 State the rejection region. (If the test is one-tailed, enter NONE for the unused region. Round your answers to two decimal places.) x2 > x² State the conclusion. H, is rejected. There is sufficient evidence to indicate that the population variance is different from 0.8. H, is rejected. There is insufficient evidence to indicate that the population variance is different from 0.8. H, is not rejected. There is sufficient evidence to indicate that the population variance is different from 0.8. O Ho is not rejected. There is insufficient evidence to indicate that the population variance is different from 0.8.

Uestion Help For the following claim, find the null and alternative hypotheses, test statistic, critical value, and draw a conclusion. Assume that a simple random sample has been selected from a normally distributed population. Answer parts a-d. Claim: The mean IQ score of statistics professors is less than 116. Sample data: n= 17, x= 113, s 6. The significance level is a = 0.05, / Click the icon to view a table of critical t-values.

I only need help with the marked sections, thank you for the help I don’t know what went wrong

I need help only with the lat part of the exercise

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 Ho : p 0.3 vs H,: p < 0.3 using the sample results p = 0.20 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 i
