Question - A study is made to see if increasing the substrate concentration has an appreciable effect on the
velocity of a chemical reaction. With a substrate concentration of 1.5 moles per liter, the reaction was
run 15 times with an average velocity of 7.5 micromoles per 30 minutes and a standard deviation of
1.5. With a substrate concentration of 2.0 moles per liter, 12 runs were made, yielding an average
velocity of 8.8 micromoles per 30 minutes and a sample standard deviation of 1.2. Is there any reason
to believe that this increase in substrate concentration causes an increase in the mean velocity by
more than 0.5 micro mole per 30 minutes Use a 0.01 level of significance and assume the populations
to be approximately normally distributed ...Read More with equal variances? ...Read Less
