Question

1. true or false 10 points. in a frequency - distribution table, it is typically the case that you see the x column on the left and the f column on the right. true false 2. multiple choice 10 points. what is the total number of scores (n) for the distribution shown in the following frequency - distribution table? x f 4 3 3 5 2 4 1 2 4 10 14 37 none of the above

Explanation:

Step1: Recall frequency - distribution table convention

In a frequency - distribution table, the variable values (usually denoted as \(X\)) are typically listed in the left - hand column and the frequencies (denoted as \(f\)) are listed in the right - hand column. So, for the first question, the statement is True.

Step2: Calculate total number of scores

The total number of scores \(N\) in a frequency - distribution table is the sum of all frequencies. Given \(f_1 = 3\) (for \(X = 4\)), \(f_2=5\) (for \(X = 3\)), \(f_3 = 4\) (for \(X = 2\)), and \(f_4 = 2\) (for \(X = 1\)). Then \(N=f_1 + f_2+f_3+f_4=3 + 5+4+2\).

Step3: Perform addition

\(3+5+4+2=(3 + 5)+4+2=8+4+2=(8 + 4)+2=12+2 = 14\).

Answer:

1. True
2. C. 14
