This is a sample question we received. I can't really figure out how to statistically show that this data is normally distributed. We are to used the chi-square method and these are the steps we are to follow:
- Use the hypothesized distribution to create expected values for each bin.
- Use the observed and expected values to create a chi-squared value.
- Compare this computed chi-squared value with the chi-squared value from a table, using the appropriate number of degrees of freedom for this problem and the significance level.
- Based on the relationship between the computed chi-squared and the table's chi-squared values, accept or reject the hypothesis.
I have never used this method and was wondering if someone could show me how to work through a problem like this. Thanks!
