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.

(a)The verbal scores on the SAT are regularly distributed.

(b) The SAT Math results follow a normal distribution.

Step by step solution

01

Part (a) Step 1: Given information

Given in the question that, 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.

we need to find that whether the SAT verbal scores for this class appear to be approximately normally distributed

02

Part (a) Step 2: Explanation

The MINITAB can be used to create a histogram for SAT verbal scores as follows:

Step 1: Select Graph > Histogram from the drop-down menu.

Step 2: Select Simple, then click OK.

Step 3: In the Graph variables section, type the matching Verbal column.

Step 4: Click the OK button. The MINITAB output can be represented as follows:

The SAT verbal scores are nearly symmetric, as can be seen in the above histogram. To put it another way, it's a symmetric distribution. As a result, the verbal scores on the Sat are regularly distributed.

03

Part (b) Step 1: Given information

Given in the question that, 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 of800. Summary results for the scores are published by the College Entranee Examination Beard in Collexe Round Seniors. In one high school graduating class, the SAT scores are as provided on the WeissStats site.

we need to explain that whether the SAT math scores for this class appear to be approximately normally distributed.

Part (b) Step 2: Explanation

The MINITAB can be used to create a histogram for SAT Math scores as follows:

Step 1: Select Graph > Histogram from the drop-down menu.

Step 2: Select Simple, then click OK.

Step 3: In the Graph variables section, type the matching Math column.

Step 4: Click OK The MINITAB output can be represented in the following way:

The SAT Math scores are approximately symmetric, as can be seen in the above histogram. To put it another way, it's a symmetric distribution. As a result, the SAT Math results follow a normal distribution.

From the U.S. Census Bureau, in the document International Data Base, we obtained data on the total fertility rates for women in various countries. Those data are presented on the WeissStats site. The total fertility rate gives the average number of children that would be born if all women in a given country lived to the end of their childbearing years and, at each year of age, they experienced the birth rates occurring in the specified year. Use the technology of your choice to decide whether total fertility rates for countries appear to be approximately normally distributed. Explain your answer.

Arterial Cord path. Umbilical cord blood analysis immediately after delivery is one way to measure the health of an infant after birth. Researchers G. Natalucci et al used it as a predictor of brain maturation of preterm infants in the article "Functional Brain

Maturation Assessed During Early Life Correlates with Anatomical Brain Maturation at Term-Equivalent Age in Preterm Infants " (Proly. are Resend, Vol. 74. No. 1. pp. 68-74). Based on this study. we will assume that, for preterm infants, the pH level of the arterial cord (one vessel in the umbilical cord) is normally distributed with a mean of 7.32 and a standard deviation of 0.1. Find the percentage of preterm infants who have arterial cord pH levels

a. between 7.0 and 7.5.

b. over 7.4.

A variable is normally distributed with a mean 68and standard deviation 10. Find the percentage of all possible values of the variable that

a. lie between 73and 80.

h. are at least 75.

c. are at most 90.

Determine the two z-scores that divide the area under the standard normal curve into a middle 0.99area and two outside0.005 areas.

Find the following z-scores.

a. Z0.03

b.z0.005
