Let us suppose we have data on the absorbency of paper towels that were produced by two different manufacturing processes. From process 1, the sample size was 10 and had a mean and standard deviation of 190 and 15, respectively. From process 2, the sample size was 4 with a mean and standard deviation of 350 and 50, respectively. Find a 95% confidence interval on the difference in the towels' mean absorbency produced by the two processes. Assume the standard deviations are estimated from the data. Round your answers to two decimal places (e.g. 98.76). eTextbook and Media How would you interpret this CI? O The hypothesis test for the equality of means would not reject the null hypothesis (that the means do not differ) at a = 0.05. O The hypothesis test for the equality of means would reject the null hypothesis (that the means do not differ) at a = 0.05. eTextbook and Media Is the value zero in the Cl? O Yes, zero is contained in this interval. O No, zero is not contained in this interval. eTextbook and Media
