Assume all conditions for inference have been met, based on the confidence interval, the claim that is supported is that;
More than half of all people prefer texting.
<h3>Understanding Confidence Intervals</h3>
We are given;
Confidence Level; CL = 95%
Margin of error; MOE = 3%
Since 56 percent of the respondents prefer to use cell phones for texting rather than for making phone calls. It means that; x' = 56%
Thus;
CI = x' ± MOE
CI = 56% ± 3%
CI = 53% OR 59%
Thus, in conclusion we can say that more than half of the people prefer texting
