o check the activation level of data scientists, a population of data scientists was asked to play games for a fixed time duration and their brain activation levels were tested. The outcome of this research stated that playing the mobile games for a fixed time duration improved the concentration level with an average brain activation level of 100 units. If a sample of 12 data scientists were tested for the same experiment, the brain activation levels were reported as follows: 105, 90, 91, 96, 96, 91, 100, 105, 99, 107, 103 and 92 a. Does this data suggest that the population mean reading for the brain activation level under the given conditions differs from 100? State and test the appropriate hypotheses using a significance level of 0.05. b. Find the 90% confidence interval, and check whether the above given sample lies within this interval or not?
