7.7 Consider Mendel’s experimental data in Table 1.1 shown at page 9.

(a) Consider the data that pertain to the case of “Long vs. short stem.” Write an expression for the probability of making that measurement, assuming Mendel’s hypothesis of independent assortment. You do not need to evaluate the expression.

(b) Using the distribution function that pertains to that measurement, determine the mean and variance of the parent distribution. Using the Gaussian approximation for this distribution, determine if the null hypothesis that the measurement is drawn from the parent distribution is compatible with the data at the 68%

confidence level.
