_________________________________________________

     Value:                  1 or 2     3 or 4        5         6   

Observed Count:     405         420        190     185

What statistic do you need to compute to obtain the appropriate P-value? Provide the formula with the numbers plugged in! For example (NOT the correct answer!) 2 * 405 + 4/420 - 185/190

Answer 1

The answer is:

The Chi-Squared statistic is required to compute the P-value:

We would actually use chi-square goodness of fit test here:
