A study of 837 adults was conducted to understand the behavioral shift of consumers' TV viewing experience. The study found that 487 adults owned streaming enabled TVs, including smart TVs and video streaming devices. The authors of the study imply that the survey proves that more than half of all adults own streaming enabled TVs, including smart TVs and video streaming devices. Complete parts (a) through (d). 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 adults own streaming enabled TVs, including smart TVs and video streaming devices. Determine the null hypothesis, Ho, and the alternative hypothesis, H. Ho: Hy : (Type integers or decimals. Do not round.) What are the level of significance, a, and sample size, n? The level of significance is . The sample size is]. (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. A. Use the t distribution with degrees of freedom and the tSTAT test statistic. (Type a whole number.) O B. Use the normal distribution and the ZSTAT test statistic. Determine the test statistic. The test statistic is. (Round to two decimal places as needed.) Determine the p-value. The p-value is. (Round to three decimal places as needed.) State the conclusion.State the conclusion. the null hypothesis. There sufficient evidence to conclude that the proportion of adults that own streaming enabled TVs, including smart TVs and video streaming devices is (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 valid. There sufficient evidence to conclude that more than half of all adults own streaming enabled TVs, including smart TVs and video streaming devices because the p-value is the level of Significance. c. Suppose the study found that 428 adults own streaming enabled TVs, including smart TVs and video streaming devices. Repeat parts (a) and (b), using the same hypotheses. Determine the test statistic. The test statistic is. (Round to two decimal places as needed.) Determine the p-value. The p-value is. (Round to three decimal places as needed.) State the conclusion. the null hypothesis. The claim valid. There sufficient evidence to conclude more than half of all adults own streaming enabled TVs, including smart TVs and video streaming devices because the p-value is the level of significance. d. Compare the results of parts (b) and (c). The results of part (b) are the results of part (c). Lowering the number of adults that own streaming enabled TVs, including smart TVs and video streaming devices the p-value
