Determinez0.33

Short Answer

Expert verified

The z-score under the usual normal curve with the area 0.33 to its right is around 0.67.

Step by step solution

01

Given information

The given area is0.33.

02

Explanation

The given area is 0.33

The z-score with 0.33the area under the standard normal curve to its right is equal to the z-score with 1-0.33=0.67the area to its left.

Begin by looking for the 0.67area in the table's body. The appropriate z-score will be 0.44.

As a result, the z-score under the usual normal curve with the area 0.33to its right is around 0.44, which may be depicted as

The relevant portion of the standard normal table is shown below

Each year, thousands of high school students bound for college take the Scholastic Assessment Test (SAT). This test measures the verbal and mathematical abilities of prospective college students. Student scores are reported on a scale that ranges from a low of 200to a high of 800. Summary results for the scores are published by the College Entrance Examination Board in College Bound Seniors. In one high school graduating class, the SAT scores are as provided on the WeissStats site. Use the technology of your choice to answer the following questions.

a. Do the SAT verbal scores for this class appear to be approximately normally distributed? Explain your answer.

b. Do the SAT math scores for this class appear to be approximately normally distributed? Explain your answer.
