Perform the goodness of fit test at the 10% significance level. Are the residuals normally distributed?
I have the formula as the sum of (((a-e)^2)/e)))
a=sample frequency
e=total number of residuals*area under pdf for that class
but how do I find area under probability distribution function for class width? Pleeeeeasee help
