The value of z is 0.8770. This answer was derived from information in the question, which states that the value of z is 0.8770. Granted, I don't understand what is meant by "cumulative standardized normal distribution." I only passed statistics because the professor felt sorry for me.

Answer from: destinymccray35

The value of is $\boxed{1.17}$ for the value of the cumulative standardized normal distribution at is 0.8770 .

Further explanation:

Given:

The cumulative standardized normal distribution is 0.8770 .

Concept used:

The normal distribution that has mean zero and variance one is called as standard normal distribution.

The random variable X follows standard normal distribution with mean zero and variance one.

\boxed{X \sim N\left( {0,1} \right)}

Then the value of can be obtained as,

$\boxed{Z = \frac{{X - \mu }}{\sigma }}$

Calculation:

The normal distribution is symmetric.

The standard normal distribution is bell shaped curve and it also a symmetric curve.

The cumulative standardized normal distribution is 0.8770 it is area under the curve.

The probability of a number less than value is 0.8770 .

From the table the approximate value of the is $\boxed{1.17}$ .
