The value of the cumulative standardized normal distribution at z is 0.8770. what is the value of z?

The value of is for the value of the cumulative standardized normal distribution at is .

Further explanation:

Given:

The cumulative standardized normal distribution is .

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,

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 it is area under the curve.

The probability of a number less than value is .

From the table the approximate value of the is .

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
