Thank you for posting your question here. Below is the sum of the pattern above using the summation notation.
<span>4 + 5 + 14 + 23 +...+1 31 = <span>∑<span>n=0</span>15</span>(−4)+n⋅9
</span>Summation Notation<span>. Often mathematical formula require the addition of many variables </span>Summation<span> or sigma </span>notation<span> is a convenient and simple form of shorthand used to give a concise expression for a sum of the values of a variable.</span>
If we divide 15 by 42:
15 / 42 = 0.3571 or 35.71%
Since the level of significance is 0.05, an accuracy of 35.71%, based on the data, the results of the polygraph suggest that the polygraphs are not effective in distinguishing between truths and lies.
