For a study on the average intelligence level (IQ values) of five-year-old normal children, the mean IQ value was calculated as 100 and the standard deviation as 14 in 64 children. If it is known that the distribution of intelligence levels of all children in the region fits the normal distribution, calculate the 99% confidence interval for all children? Briefly interpret the results. If the confidence interval calculated for the same variable under the same conditions is (93,028 - 106,972), what is the probability of the trust level here? Is it true that children's intelligence levels are 110 according to the calculated confidence interval? Please explain.( note: please write clearly)
