1. Let Z be a random variable with a standard normal distribution. Calculate: P(Z ≥− 1.47)= ? P(Z k)=0.49, then the value of k is: ? Note: Answer with at least 4 decimal places

1. Let Z be a random variable with a standard normal distribution. Calculate:

• P(Z ≥− 1.47)= ?

P(Z < 1.49)="">

P(2.16 ≤ Z ≤ 2.56)= ?

P(Z ≤− 2.28 or Z ≥ 0.02)= ?

If P(Z < k)="0.62," then="" the="" value="" of="" k="" is:="">

If P(Z > k)=0.49, then the value of k is: ?

Note: Answer with at least 4 decimal places
