Question

A university Plant Science department has a project involving genetics and the amounts of amylose (unbranched starch) and amylopectin (branched starch) in peas. (This could prove to be important for diabetics.) The starch content of one genetic variety of pea was analyzed using 4 samples and found the mean to be 171 g/kg (this is grams of amylose per kg of pea) with a standard deviation of 4. Another pea analysis, using 5 pea samples, reveals wan average amylose as 242 g/kg with a standard deviation of 12. Would you consider these two standard deviations to be significantly different at the 95% confidence interval?
