Answer 1

Ans . Paired sample t-test

Reason: Paired Sample t-test is used when we are interested in the difference between two variables of same subject( quality of digital wallet service).Often the two variables are separated by time ( different age groups).

Independent Sample t-test

It is used to compare means of two independent data. But here, it is dependent data. Since aged people or young people's perception could affect another's perception.

One Sample t-test

It is used to test the difference between sample mean and population mean.

One way ANOVA

It is used to determine whether there are any statistically significant differences between two or more samples. But we use it when there are minimum three groups instead of two.
