Run a set of nested models with the PewShop dataset that will test this idea: younger people tend to use technology more to shop (use the shop index), but this is only because (as we’ve seen) younger people are more likely to have smartphones than are older people. Create a table that presents the nested models and explain your findings by doing four examples:

a. a 25-year-old who doesn’t have a smartphone

b. a 25-year old who does have a smartphone

c. an 80-year-old who doesn’t have a smartphone

d. an 80-year old who does have a smartphone
