The assumptions made for confidence intervals are fulfilled here since it is safe to say that the sample is
random and not biased. It is also evident that the observations of the sample are independent of each other
since they are all different people. These conditions on the design of this experiment are fulfilled. The
conditions on the form of the population distribution are also fulfilled since the sample size is greater than
30 and the graphs above display the normality of the probability distribution.
