The results of a recent study on retail apps and buying habits indicate that tablet users (55%) are almost twice as likely as smartphone users (28%) to use their device to purchase products and services. The findings also reveal that nearly half of all mobile shoppers are interested in using apps instead of a mobile browser (45% of tablet shoppers and 49% of smartphone shoppers). The research is based on an online survey with a sample of 1,003 consumers. Identify potential concerns with coverage, non response, sampling, and measurement errors. Select all that apply. A. The sample is a self-selecting sample of people who responded online, so there is an undefined nonresponse error. B. The survey does not cover anyone without a computer or internet access, so there is a coverage error. C. Since this is not a random sample, there is no sampling error. D. Since this is not a random sample, sampling error cannot be determined. E. Anyone with a computer could respond, so there is no nonresponse error. F. Since any small business owner could respond, there is no coverage error. G. Since the survey consists of yes or no questions, there is no possibility of measurement error. H. Measurement error is possible if a respondent incorrectly answers one of the survey questions. g
