According to chemical engineering, an important property of fiber is its water absorbency. the average percent absorbency of 12 randomly selected pieces of cotton fiber was found to be 20 with a standard deviation of 1.5. a random sample of 10 pieces of acetate yielded an average percent of 12 with a standard deviation of 1.25. is there strong evidence that the population mean percent absorbency is significantly higher for cotton fiber than for acetate? assume that the percent absorbency is approximately normally distributed and that the population variances in percent absorbency for the two fibers are the same. use a significance level of 0.05.
