How common are financial cost or contractual constraints associated with smartphone ownership? A survey of smartphone owners found that 48% of the 18 to 29 year old customers, 38% of the 30 to 49 year old customers, 25% of the 50 to 64 year old customers, and 19% of the 65 year old plus customers have reached the maximum amount of data they are allowed as part of their plan, at least on occasion. Suppose the survey was based on 200 smartphone users in each age category.

At the 0.05 level of significance, is there evidence of a difference among the age groups in the proportion of smartphone owners who have reached the maximum amount of data they are allowed to use as part of their plan, at least on occasion?
Determine the p-value in (a) and interpret its meaning.
If appropriate, use the Maracuilo procedure at .05 to determine which age groups differ. State which ones differ and why statistically.
