PLEASE INCLUDE TI84/83 CALCULATOR PROCESS/FUNCTIONS USED TO SOLVE. THANK YOU!!!!

1 1 141% addition, it might be a good idea to let me know what your hypotheses were, what calculator function you used, and the decision (reject Ho or fail to reject Ho.) 1. It has been suggested that abnormal male children tend to occur more often in children born to older than average mothers. Case histories of 20 abnormal males were obtained. The mean age of the 20 mothers of these children was 31.45 and the sample standard deviation was 9.049 years. It is known that the mean age at which mothers in the general population give birth is 28 years. Does the sample give sufficient evidence to support the claim that the mean age of mothers of abnormal male children is greater than 28 years? Use a = 0.05. Assume the ages of mothers of abnormal male children have a normal distribution
