question 1
1 pts
find ( p(zleq - 1.24)=)______
question 2
1 pts
find ( p(zlt0.03)=)______

Explanation:

Step1: Use the standard normal distribution table

For \(P(Z\leq - 1.24)\), look up the value in the standard normal table. The table gives the cumulative probability from the left.
For \(z=-1.24\), in the standard normal table (negative \(z\)-scores), we find the value. The row for \(z = - 1.2\) and the column for \(0.04\). The value is \(0.1075\)

For \(P(Z < 0.03)\), look up the value in the standard normal table. The row for \(z = 0.0\) and the column for \(0.03\). The value is \(0.5120\)

Answer:

Question 1: \(0.1075\)
Question 2: \(0.5120\)
