Signficant change in the deviation of the ages

Reference no: EM13330703

last year the standard devation of the ages of student at uawas 1.81 years recently a sample of 10 students had a standarddevation of 2.1 years. we are interested in testing to see if therehas been a signficant change in the deviation of the ages of thestudents at UA.

At 95% confidence the null hypothesis should?
