WebFind the critical chi-square value using the chi squared table. Step 1: Subtract 1 from the number of categories to get the degrees of freedom. Categories are blue corn and yellow corn, so df = 2-1 = 1. Step 2: Look up your degrees of freedom and probability in the chi squared table. The probability is given to you in the question (5% or 0.05). WebA distribution is said to be skewed if the curve shifts to right or left from a normal bell-shaped distribution. The symmetrical curve has zero skewness. That is the normal distribution has a skew of zero. A skewed distribution has a tail at either of the sides. A tail refers to the tapering off on one side of the graph.
