A university conducted a study of online adults that included 404 tablet owners. The study found that 208 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, Ho, and the alternative hypothesis, H₁. Ho: π ≤ 0.50 0.50 H₁: π (Type integers or decimals. Do not round.) What are the level of significance, x, and sample size, n? The level of significance is 0.05. The sample size is 404. (Type integers or decimals. Do not round.) Determine the appropriate sampling distribution and test statistic. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. Use the t distribution with B. Use the normal distribution and the ZSTAT test statistic. G degrees of freedom and the tSTAT test statistic. Determine the test statistic. The test statistic is (Round to two decimal places as needed.)

---
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, H₀, and the alternative hypothesis, H₁.
H₀: π ≤ 0.50
H₁: π > 0.50
(Type integers or decimals. Do not round.)
What are the level of significance, α, and sample size, n?
The level of significance is 0.05. The sample size is 404.
(Type integers or decimals. Do not round.)
