A cognitive psychologist has developed a cognitive training procedure to improve the people's cognitive abilities. Following the training, a random sample of 121 older adults take a cognitive abilities test. The average score is 108, with s = 16.25. Assume the population mean for healthy middle-aged adults is 100 on the test. Test that hypothesis that training significantly improved scores. Test that hypothesis that training significantly improved scores. Calculate CI using a 95% CI interval (alpha .05). What is the LOWER CI value (part of step 6)? Round out 2 decimal places.
