Transcribed Image Text:How long it takes paint to dry can have an impact on the production capacity of a business. In May 2018, Deal's Auto Body & Paint in Prescott, Arizona,
invested in a paint-drying robot to speed up its process (The Daily Courier website, https://www.dcourier.com/photos/2018/may/26/984960336/). An
interesting question is, "Do all paint-drying robots have the same drying time?" To test this, suppose we sample five drying times for each of different brands
of paint-drying robots. The time in minutes until the paint was dry enough for a second coat to be applied was recorded. The following data were obtained.
