Hi guys,nice to meet you,its my first time here(Sry for my english) !!

In some days i will be examed on statistic 2 and i have problem with the following problems :

My teacher says to answer if the following problems are true or false and to explain why(to prove it with calculations)

- 2 *z
_{0.035}= z_{0.070}- z
_{0.05}>z_{0.07}- z
_{0.035 >}t_{32 0.035}- z
_{0.035 = }0.5*Z_{0.070}

How i solve them ?

Thank you.
