Question

Health insurers are beginning to offer telemedicine services online that replace the common office visit. Wellpoint provides a video service that allows subscribers to connect with a physician online and receive prescribed treatments. Wellpoint claims that users of its LiveHealth Online service saved a significant amount of money on a typical visit. The data shown below ($), for a sample of 20 online doctor visits, are consistent with the savings per visit reported by Wellpoint.

91	34	39
107	83	57
55	50	39
76	46	94
93	75	71
80	90	98
51	83

Assuming the population is roughly symmetric, construct a 95% confidence interval for the mean savings for a televisit to the doctor as opposed to an office visit (to 2 decimals).

95% confidence interval: $ to $ per visit

Answer 1

Hence, we can write

a 95% confidence interval for the mean savings for a tele-visit to the doctor as opposed to an office visit
