Question
A nationwide survey asked 500 randomly selected adults, “Do you like to eat “everything" pizza?” They defined an everything pizza as a pizza that contains at least 5 different toppings. Of the 500 adults surveyed, 121 replied that they like everything pizza. A 99% confidence interval is constructed to estimate the true proportion of all adults who like everything pizza. Which of the following steps, if any, contain an error? Conclude: We are 99% confident that the interval from 0.193 to 0.291 captures the proportion of adults in the survey who responded that they like everything pizza. State: We want to estimate p = the proportion of all adults who like everything pizza at a 99% confidence level. Plan: One-sample z interval for p. Random? Random sample of 500 adults. Yes! Large Counts? 121 ≥ 10and379 ≥ 10. Yes! Do: (0.193, 0.291) None of the steps contain an error.
