statistics shading a region and finding its standard normal probability answer the following. (a) the standard normal curve is graphed below. shade the region under the standard normal curve to the left of z = - 1.00. (b) use this table or the aleks calculator to find the area under the standard normal curve to the left of z = - 1.00. give your answer to four decimal places (for example, 0.1234).

Answer

Explanation:

Step1: Use standard - normal table

The standard - normal table gives the cumulative distribution function values for the standard normal distribution $Z\sim N(0,1)$. We want to find $P(Z < - 1.00)$.

Step2: Look up the value

Looking up $z=-1.00$ in the standard - normal table (the left - most column for the integer and first decimal place, and the top row for the second decimal place), we find that the value corresponding to $z =-1.00$ is $0.1587$.

Answer:

$0.1587$
