Smartphone use: In a Pew Research report titled, “U. S. Smartphone Use in 2015” the author states that 48% of smartphone-dependent Americans had to cancel or shut off their cell phone service for a period of time because the cost of maintaining that service was a financial hardship. “Smartphone dependent” is defined as owning a smartphone, but lacking any other type of high-speed access at home and having limited options for going online other than their cell phone. Let’s assume this is true and set up a simulation to randomly sample 50 adults from this population. For each sample, we calculate the proportion of smartphone-dependent adults who had to cancel or shut off their cell phone service. We’ll repeat this process 1,000 times. The dotplot of the resulting 1,000 proportion calculations is displayed below.
