b. Based on the result in part (a), is the claim implied by the authors valid? The claim is not valid. There is not sufficient evidence to conclude that more than half of all tablet owners use their tablet while watching TV at least once per day because the p-value is greater than the level of significance. c. Suppose the study found that 239 tablet owners use their tablet while watching TV at least once per day. Repeat parts (a) and (b). What is the test statistic? The test statistic is. (Round to two decimal places as needed.)

need help with c

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.** - **The test statistic is** 0.60. *(Round to two decimal places as needed.)* - **Determine the p-value.** **The p-value is** 0.2743. *(Round to four decimal places as needed.)* - **State the conclusion.** **Do not reject** the null hypothesis. There **is not** sufficient evidence to conclude that the proportion of tablet owners who use their tablet while watching TV at least once per day is greater than **0.50**. *(Type an integer or a decimal. Do not round.)* **b. Based on the result in part (a), is the claim implied by the authors valid?** - The claim **is not** valid. There **is not** sufficient evidence to conclude that more than half of all tablet owners use their tablet while watching TV at least once per day because the p-value is **greater than** the level of significance. **c. Suppose the study found that 239 tablet owners use their tablet while watching TV at least once per day. Repeat parts (a) and (b). What is the test statistic?** - **The test statistic is** __. *(Round to two decimal places as needed.)*
