A university conducted a study of online adults that included 419 tablet owners. The study found that 215 tablet owners use their tablet while watching TV. The authors of the report imply that the survey proves that more than half of all tablet owners use their tablet while watching TV at least once per day. Complete parts (a) through (d) below.

a. Use the five-step p-value approach to hypothesis testing and a 0.05 level of significance to try to prove that more than half of all tablet owners use their tablet while watching TV at least once per day. Determine the null hypothesis, Upper H0, and the alternative hypothesis, Upper H1

b) Suppose the study found that 245 tablet owners use their tablet while watching TV at least once per day. Repeat the 5 step process. What is the test statistic?
