I am unable to perform a z-test analysis. Every time I serve, it shows I have entered non-numeric data. I don't know what it is. Could you please help me out with this? The data also contains negative numbers.

@Tabish650 Select the cells which contain the actual numbers. Does Excel show a small icon next to the selected numbers? If yes, click it and select "Convert to number"
