we can analyse this using the excel , please note spss is a commercial software.

However , the findings and output will remain the same

We enter the data in excel and then goto data > data analysis tab and select t test , please see the excel screenshots below

df = 26 , p value - 0.0121 and t stat = -2.696

as the p value is less tha 0.05 , hence at alpha of 0.05 the results are statisitcally signficant and we conclude that the mean values of the 2 groups are signficantly different
