Question

For each of the following questions, indicate whether it is best assessed by using a confidence interval or a hypothesis test or whether statistical inference is not relevant to answer it. (answer all please!!)

Do a majority of adults riding a bicycle wear a helmet?
On average, how many more minutes do ladies spend in the restroom than men?
Is the median Exam 1 score for STA 270 students in section 10 any different from that of STA 270 students in section 11?
What is the average daily calorie intake of 20-year-old males?
In 2010, what percent of the US Senate voted to confirm Elena Kagan as a member of the Supreme Court?

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
