Question 5 of 13 -/ 4 View Policies Current Attempt in Progress Use the t-distribution to find a confidence interval for a difference in means u - Hz given the relevant sample results. Give the best estimate for u, - Hz, the margin of error, and the confidence interval. Assume the results come from random samples from populations that are approximately normally distributed. A 99% confidence interval for u, - 42 using the sample results I = 10.0, sı = 2.2, n = 50 and = 13.0, s2 = 5.8, n2 = 50 Enter the exact answer for the best estimate and round your answers for the margin of error and the confidence interval to two decimal places. Best estimate = i Margin of error = i Confidence interval: i to i II
Q: Using the data (provided below this question) test the hypotheses that the mean difference in writing and reading scores is zero and that the mean difference in math and science scores is zero. Use the paired-sample procedure. Use a 5% significance level if the problem doesn’t give an alpha. Note: Please only provide the t stat, p(T<=t) value and critical value. No need to explain the steps.

You wish to test the following claim (Ha) at a significance level of a = 0.001. H,:P = P2 Ha:pi > p You obtain 303 successes in a sample of size n = 488 from the first population. You obtain 159 successes in a sample of size ry = 266 from the second population. What is the test statistic for this sample? test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... O less than (or equal to) a O greater than a This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null As such, the final conclusion is that...

Find the P-value that corresponds to the given standard score, and determine whether to reject the null hypothesis at the 0.05 significance level. Is the alternative hypothesis supported? z=3.5 for H₁: μ=124.5 kilograms and H₂: μ# 124.5 kilograms The P-value is (Round to four decimal places as needed.) Determine whether the alternative hypothesis is supported at a 0.05 significance level. O A. The P-value is more than the significance level. Do not reject Ho. The alternative hypothesis is not supported. OB. The P-value is more than the significance level. Reject Ho. The alternative hypothesis is supported. OC. The P-value is less than or equal to the significance level. Reject Ho. The alternative hypothesis is supported. O D. The P-value is less than or equal to the significance level. Do not reject Ho. The alternative hypothesis is not supported.
