Use the t-distribution to find a confidence interval for a difference in means \( \mu_1 - \mu_2 \), given the relevant sample results. Give the best estimate for \( \mu_1 - \mu_2 \), 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 \( \mu_1 - \mu_2 \) using the sample results \( \bar{x}_1 = 533, \, s_1 = 114, \, n_1 = 360 \) and \( \bar{x}_2 = 468, \, s_2 = 91, \, n_2 = 200 \).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: [Input box]- Margin of error: [Input box]- Confidence interval: [Input box] to [Input box] Attempts: 2 of 4 used.
