Calculating the sample mean

The late_shipments dataset contains supply chain data on the delivery of medical supplies. Each row represents one delivery of a part. The late columns denotes whether or not the part was delivered late. A value of "Yes" means that the part was delivered late, and a value of "No" means the part was delivered on time.

Let's begin our analysis by calculating a point estimate (sample statistic), namely the proportion of late shipments.

late_shipments is available; dplyr is loaded.
