Use the t-distribution to find a confidence interval for a mean given the relevant sample results. Give the best point estimate for Hi the margin of error, and the confidence interval. Assume the results come from a random sample from a population that is aproximately normally distributed A 90% confidence interval for using the sample results X = 143.6.5 = 49.8, and n = 50 Round your answer for the point estimate to one decimal place, and your answers for the margin of error and the confidence interval to two decimal places point estimate margin of error The 90% confidence intervalls to
