You have to enter the correct df here.In a cross tabulation, df
=(r-1)(c-1) where r and c are number of rows and number of columns
respectively.
In the case of fitting the data to a distribution,df equals k -
1 - (the number of chosen parameters). It equals k - 1 if no
parameters have been chosen.
For example, if a normal distribution with a chosen (as opposed
to predetermined) mean and a chosen standard deviation is used to
calculate the expected frequencies, then df = k - 3.

The df is 3 when the mean and standard deviation used are
calculated from the sample data. When they are given in the null
hypothesis, the df should be 5. In such a case, 1. Unprotect the
sheet2. Enter the mean and standard deviation given in the null
hypothesis in cells G4 and G5.3. Change the df in cell L9 to 5.This
is the mean computed from sample data. This should be used only if
nothing is mentioned about the mean or standard deviation in the
null hypothesis. If the mean and standard deviation are specified
in the null hypothesis: 1. Unprotect the sheet2. Enter the mean and
standard deviation given in the null hypothesis in cells G4 and G5
respectively.3. Change the df in cell L9 to 5.This is the standard
deviation computed from sample data. This should be used only if
nothing is mentioned about the mean or standard deviation in the
null hypothesis. If the mean and standard deviation are specified
in the null hypothesis, 1. Unprotect the sheet2. Enter the mean and
standard deviation given in the null hypothesis in cells G4 and G5
respectively.3. Change the df in cell L9 to 5.
