answer the following. (a) the standard normal curve is graphed below. shade the region under the standard normal curve to the left of z = 2.00. (b) use this table or the aleks calculator to find the area under the standard normal curve to the left of z = 2.00. give your answer to four decimal places (for example, 0.1234).

answer the following. (a) the standard normal curve is graphed below. shade the region under the standard normal curve to the left of z = 2.00. (b) use this table or the aleks calculator to find the area under the standard normal curve to the left of z = 2.00. give your answer to four decimal places (for example, 0.1234).

Answer

Explanation:

Step1: Use standard - normal table

We look up the value of (z = 2.00) in the standard - normal table (or use a calculator with a normal - distribution function). The standard - normal table gives the cumulative distribution function value (P(Z<z)) for a standard normal random variable (Z).

Step2: Find the area

From the standard - normal table or calculator, when (z = 2.00), the area under the standard normal curve to the left of (z = 2.00) is (0.9772).

Answer:

(0.9772)
