Percent yield is expected to be less than 100% because it is:

           Percent yield = [actual yield / theoretical yield] × 100

The theoretical yield is calcualted from the stoichiometry of the chemical equation, then the actual yield cannot be greater than the theoretical yield.

A theoretical yield greater than 100% is indication of an error.

Two errors can be thought:

- A wrong measurement of the amounts of reactants or products

- The presence of impurities in the reactants that lead to the actual mass is greater than the mass if the reactant is pure.

nevsk [136]

Answer:

the answer is in the explanation

Step-by-step explanation:

we are given

          sample size n_{1} = n_{2} = 10  for each formulation

          mean  \bar{x} _{1} (formulation 1) = 121

          mean \bar{x} _{2}  (formulation 2) = 112

         s (standard deviation )  =  8 mins for  each case

        null hypothesis        H_{0}        μ2 = μ1        (both have average same time)

 alternative hypothesis   H_{1}         μ2 < μ1

          under H_{0}  the test statistics is

                                t = \frac{\bar{x}_{2} - \bar{x}_{1} }{s\sqrt{\frac{1}{n_{1} }+ \frac{1}{n_{1}} } }

                               t = \frac{112 - 121 }{8\sqrt{\frac{1}{10 }+ \frac{1}{10} } }

                                t = -2.5

                        ItI = 2.5

            The P-value at  ItI = 2.5       at \alpha = 0.05    μ = 0.010699
