Use the results from a survey of a simple random sample of 1278 adults. Among the 1278 respondents, 68% rated 3 of adults rate themselves as above average themselves as above average drivers. We want to test the claim that 5 drivers. Complete parts (a) through (c). ... 869 (Round to the nearest whole number as needed.) b. Identify the sample proportion and use the symbol that represents it. ô 4 = 0.68 (Type an integer or a decimal rounded to two decimal places as needed.) c. For the hypothesis test, identify the value used for the population proportion and use the symbol that represents it. (Type an integer or a decimal rounded to two decimal places as needed.)
