“a. P(Zleq z^*)=0.92, P(Z>z^*)=0.08”“z^*=1.4051”
“b. P(Zleq z^*)=0.28, P(Z>z^*)=0.72”“z^*=-0.5828”
“c. P(Zleq z_1^*)=0.5-0.29=0.21, P(Z<z_2^*)=0.5+0.29=0.79”
“z^*=plusmn0.8064”
So the interval is “(-0.8064, 0.8064)”
“d. P(Zleq z_1^*)=0.5-0.225=0.275, P(Z<z_2^*)=0.5+0.225=0.725”
“z^*=plusmn0.5978”
So the interval is“(-0.5978, 0.5978).”
