question 1
for a standard normal distribution, find:
p(z < -1.98)
express the probability as a decimal rounded to 4 decimal places.

Explanation:

Step1: Use z - table lookup

We use the standard normal distribution z - table. The z - table gives the cumulative probability $P(Z < z)$ for a standard normal random variable $Z$.

Step2: Find the value in the table

Looking up $z=-1.98$ in the standard normal distribution table. The table value for $z = - 1.98$ is $0.0239$.

Answer:

$0.0239$
