Use the dropdown menu to choose the Market Research Data data set. The variable descriptions are as follows:

No$.$: An arbitrary identification number assigned to each consumer surveyed

Age: The age of the survey respondent

RateNew: The respondent's rating of the new cell phone

RateCurr: The respondent's rating of their current cell phone

CurrBrand: The brand of the respondent's current cell phone

Choose a sample of $100$ observations. For the following question or analysis request, identify the appropriate hypothesis test to perform.

"Let's do a randomization check. Divide observations by their ID number in groups of $25(1-25,26-50,$ etc.$).$ We would expect only small differences in age across these groups that could be attributed to random variations. Is this the case?Data Collectlon: ANOVA Tests $1.$C
