25 peоple аre rаndоmly selected frоm а normally distributed population in order to study variance in IQ (Intelligence Quotient). The average IQ of the people selected is 100, and the standard deviation is 15. Based on this information, and a confidence level of 98%, answer the following questions.What is the value of Chi-squared right [chiR] (round to 2 decimals)What is the value of Chi-squared left [chiL] (round to 2 decimals)The confidence interval for the population standard deviation (sigma) is [conL]
