No. The expected value is the mean!
The expected value is the average of a probability distribution. It is the value that can be expected to occur on the average, in the long run.
negative nine is the value of negative nine
The chi-squared statistic is calculated by summing (O-E)2/E where E and O are the expected and observed values for some category, and the summation is carried out over all categories. The expected number of observations for any category cannot be negative, and the numerators are squares so each element in the summation is non-negative. Consequently the sum is non-negative.
The opposite is: negative (the absolute value of negative 30).
