问题如下图:
请问这道题在计算器上应该怎么按啊?我看解题结果是用excel的
NO.PZ2020010303000009问题如下Either using a Z table or the Excel function NORM.S.ST, compute Pr(-1.5 Z 0), where Z ∼ N(0, 1) Pr(Z -1.5), where Z ∼ N(0, 1) Pr(-1.5 X 0), where X ∼ N(1, 2) Pr(X 2), where X ∼ N(1, 2) e. Pr(W 12), where W ∼ N(3, 9) 43.3%. In Excel, the commanto compute this value is NORM.S.ST(0,TRUE) – NORM.S.ST(-1.5,TRUE).6.7%. In Excel, the commanto compute this value is NORM.S.ST(-1.5,TRUE).20.1%. In Excel, the commanto compute this value is NORM.S.ST((0 – 1)/SQRT(2),TRUE) – NORM.S.ST((-1.5-1)/SQRT(2),TRUE). 24.0%.
