ANOVA-customer satisfaction witb e-services provided by bank depend repondent's age

#1
Hi, I was testing the hypothesis that the satisfaction level of the respondent with respect to e-banking services provided by their bank depends upon the age of the respondents.

This is ANOVA problems however I am unable to figure out how to approach the problem. I am attaching the excel file. The file has two tabs, one is named data and the other is named legends.

Hope that helps the forum to provide me with guidance.
