Question

The data set in CATHOLIC includes test score information on over 7.000 students in the United States who were in eighth grade in 1988. The variables math 12 and read12 are scores on twelfth grade stan- dardized math and reading tests, respectively.

How many students are in the sample? Find the means and standard deviations of math12 and read12.

Answer 1

The sample size is 7,000. To find the means and standard deviations of math12 and read12, you can calculate the average and standard deviation using the data provided in the dataset.

Step-by-step explanation:

The number of students in the sample can be determined by the given information. It states that the data set includes test score information on over 7,000 students in the United States who were in eighth grade in 1988. Therefore, the sample size is 7,000.

To find the means and standard deviations of math12 and read12, we can calculate the average and standard deviation of the respective variables using the data provided in the dataset.

Once the dataset is available, we can calculate the mean and standard deviation using appropriate formulas.
