Please, compare the chi-square value with the chi-square critical value, that way I can check my results. Thank you in advance.

In the past, the blood counts were performed manu- ally using the hemocytometers with microscopic grid scoring. By properly diluting blood, counting all cells in specified squares, and multiplying by the proper conversion factor, the number of cells per cubic mil- limeter can be approximated. The Coulter principle led to the availability of Coulter counters and thereafter, the development of sophisticated automated blood-cell ana- lvzers. The level of sophistication has been rising ever since. The data sheet for red blood cell counts for 71 healthy subjects (40 female, 31 male) is available in the attached excel file. Specify with the significance level of 0.01 if the mean blood cell count is different in patients with different gender
