12. The rise of online streaming services such as Netflix and HBO Go has dramatically altered the media habits of Americans, especially young adults. A survey was conducted by interviewers at Princeton Data Sources. They selected a nationwide random sample of 384 adults and asked, "What is the primary way you watch television: cable, online streaming, or digital antenna?" The observed counts are given in the side-by-side frequency bar graphs below. Cable or satellite subscription Online streaming service Digital antenna 100 80 80- 60 40 Frequency 31 61 19 70 84 20- 15 10 0 18-29 30-49 50-64 65+ Ages (b) Which cell contributes the most to the chi-square statistic? Describe how the observed and expected counts differ for that category.
Health coverage, frequencies. The Behavioral Risk Factor Surveillance System (BRFSS) is an annual telephone survey designed to identify risk factors in the adult population and report emerging health trends. The following table summarizes two variables for the respondents: health status and health coverage, which describes whether each respondent had health insurance. Health No Coverage Yes Total Excellent 459 4,198 4,657 Very good Health Status Good Fair Poor Total 385 99 2,524 727 854 6,245 4,821 1,634 578 17,476 6,972 5,675 2,019 677 20,000 If one individual is drawn at random, what is the probability that the respondent has excellent health or doesn't have health coverage?

Percent of Population Obese Number of Countries 11.4–20.45 32 20.45–29.45 11 29.45–38.45 5 38.45–47.45 0 47.45–56.45 3 56.45–65.45 2 65.45–74.45 1 74.45–83.45 1 (a) What is the best estimate of the average obesity percentage for these countries? (Round your answer to two decimal places.)(b) The United States has an average obesity rate of 33.9%. Is this rate above average or below? (Round your answers to two decimal places.) Since the average for the United Sates is 33.9%, compared to the average obesity rate of %, the United States has an obesity rate % higher than average. (c) How does the United States compare to other countries? (Assume that the United States is included in the data. Assume the other countries in the range 29.45–38.45 have higher obesity than the United States.) 1. The United States has an obesity rate…
