New Age Solar sells and installs solar panels for residential homes. The company$$s sales representatives contact and pay a personal visit to potential customers to present the benefits of installing solar panels. This high$-$touch approach works well as the customers feel that they receive personal services that meet their individual needs, but it is more expensive than other, mass$-$marketing approaches. The company wants to be very strategic about visiting potential customers who are more likely to install solar panels. The company has compiled the accompanying data file about past home visits by sales reps. The data include the age and annual income $($in $$1,000$s$)$ of the potential customer and whether or not the customer purchases the solar panels $($Install: Y$/$N$).$
