anyone help?

In this exercise we will explore the link between the standard normal distribution, Z ~ N(mean=0, variance=1), and the Student's t distribution, X ~ Student's t(d.o.f.=n-1). Calculate the following using the Excel function =NORM.INV or =T.INV as appropriate. Calculate the values of X, where X ~ Students t(d.o.f.=n-1), for which 2% of the data lies in the lower tail and 2% lies in the upper tail, and where n=10 such that X ~ Students t(d.o.f.=9). (answer in absolute value and to 2 decimal places) Answer. Calculate the values of X, where X ~ Students t(d.o.f.=n-1), for which 2% of the data lies in the lower tail and 2% lies in the upper tail, and where n=20 such that X ~ Students t(d.o.f.=19). (answer in absolute value and to 2 decimal places) Answer: Calculate the values of X, where X ~ Students t(d.o.f.=n-1), for which 2% of the data lies in the lower tail and 2% lies in the upper tail, and where n=50 such that X ~ Students t(d.o.f.=49). (answer in absolute value and to 2 decimal places)
