Ivan is the IT director of Memorial Hospital. He conducts an ecperiment to detect the rate for data entry of diagnostic codes. He notes that give errors were made every 5 entries. The observed probability of an error is
5 % (5/100x100)
Ivan is concerned about the operator errors in the hospital staff's use of the record system. He runs anumber of ecperiments to track the number of errors made by members after different amounts of training. He observes a linear relationship: the fewer errors. He then runs a linear regression and finds that the conefficient is 0.79. What should he conclude?
More training will reduce the number of errors
Ivan is interested in replacing the servers for his electronic helath records. 1,000 response time samples from two server vendors, Electro and SuperFast. Electro's server is 1.01 seconds, and the mean time of SuperFast's server is 1.00. Ivan finds that the time differences are statistically significant. The cost of 10 percent less than the cost of superfasts server How should ivan decide?
Although electro's server is slightly slower, the difference is not practivally significant. Buy the lowest server
