Question

a company must decide which of two delivery services it will contract with. during a recent trial period, the company shipped numerous packages with each service and kept track of if any deliveries did not arrive on time. the data obtained are shown in the contingency table below.

delivery service	count	late	on time	total
pack rats	2	154	156
pigeon express	12	170	182
total	15	406	421

the company wants to know which delivery service had the lowest percentage of late deliveries. in this situation, what is the response variable?

delivery service

timeliness (late, on time)

package type

Explanation:

A response variable is what is being measured or observed. Here, the company is interested in the timeliness of deliveries (late or on - time) for each delivery service. The delivery service is the explanatory variable, and package type is not mentioned in the context of the study. So, timeliness is the response variable.

Answer:

Timeliness (Late, On Time)
