A student working on a report about scientists decides to find the 96% confidence interval for the difference in mean age at the time of science discovery for Italian scientists versus Spanish scientists. The student determines the ages at the time of science discovery for members of both groups, which include all Italian and Spanish scientists, and uses a calculator to find the 96% confidence interval based on the t distribution. Why is this procedure not appropriate in this context

Me max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
