Assume all conditions for inference have been met, based on the confidence interval, the claim that is supported is that;

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%
