7) Before the 2003 Super Bowl, ABC predicted that 22% of the Super Bowl audience would express an interest in seeing one of its forthcoming new television shows, including 8 Simple Rules, Are You Hot, and Dragnet. ABC ran commercials for these television shows during the Super Bowl. The day after the Super Bowl, Intermedia Advertising Group of New York sampled 1532 viewers who saw the commercials and found that 414 said that they would watch one of the ABC advertised television shows (The Wall Street Journal, January 30, 2003). a) What is the point estimate of the proportion of the audience that said they would watch the television shows after seeing the television commercials? b) At ? = 0.05, determine whether the intent to watch the ABC television shows significantly increased after seeing the television commercials. Formulate the appropriate hypotheses, compute the p-value, and state your conclusion.

Step 1
The point estimate is the sample proportion, which can be calculated as: Sample proportion = (Number of people who said they would watch the shows) / (Total number of people sampled) Sample proportion = 414 / 1532 Now, we need to test whether the intent to Show more…

Before the 2003 Super Bowl, ABC predicted that 22% of the Super Bowl audience would express an interest in seeing one of its forthcoming new television shows, including "8 Simple Rules", "Are You Hot?", and "Dragnet". ABC ran commercials for these television shows during the Super Bowl. The day after the Super Bowl, Intermediale Advertising Group of New York sampled 1532 viewers who saw the commercials and found that 414 said that they would watch one of the ABC advertised television shows (The Wall Street Journal, January 30, 2003). What is the point estimate of the proportion of the audience that said they would watch the television shows after seeing the television commercials? Using a significance level of 0.05, determine whether the intent to watch the ABC television shows significantly increased after seeing the television commercials. Formulate the appropriate hypotheses, compute the p-value, and state your conclusion.

In a recent Super Bowl, a TV network predicted that 44 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 112 people who saw the commercials and found that 48 of them said they would watch one of the television shows. Suppose you are have the following null and alternative hypotheses for a test you are running: H0 : p = 0.44 Ha : p ≠ 0.44 Calculate the test statistic, rounded to 3 decimal places.

In a recent Super Bowl, a TV network predicted that 41% of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, an Advertising Group sampled 110 people who saw the commercials and found that 41 of them said they would watch one of the television shows. Suppose you have the following null and alternative hypotheses for a test you are running: H0: p = 0.41 Ha: p ≠ 0.41 (a) Calculate the sample test statistic: p̂ = (b) Calculate the standardized test statistic (the z-score). z =
