Question

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.

Alcohol abuse has been described by college presidents as the number one problem on campus, and it is an important cause of death in young adults. How common is it? A survey of 119 randomly selected U.S. college students collected information on drinking behavior and alcohol-related problems. The researchers defined “frequent binge drinking” as having five or more drinks in a row three or more times in the past two weeks. According to this definition, 41 students were classified as frequent binge drinkers. Use the data to construct and interpret a 98% confidence interval for the percentage of students who are “frequent binge drinking”. Procedure: Assumptions: (select everything that applies) Population standard deviation is unknown Population standard deviation is known Sample size is greater than 30 Normal population The number of positive and negative responses are both greater than 10 Simple random sample Unknown parameter:

The Health Behaviour in School-Aged Children (HSBC) network collects data on various behaviors of preteen and teenage children. In 2006, the HSBC network surveyed a randomly selected sample of 638 preteen and teenage boys in Greenland to determine what proportion of students were bullied at least twice per month in the previous few months. In the sample, 147 students were bullied at least twice per month, and 491 students were bullied less than twice per month. The HSBC network wants to construct a 95% confidence interval for p, the proportion of preteen and teenage boys who are bullied at least twice per month in Greenland. Have the requirements for a large-sample z-confidence interval been met? Mark all of the following requirements that have been met with yes, and the requirements that have not been met with no. O O The sample is a simple random sample. The parameter of interest is categorical with two possible outcomes, which are considered success and failure. When the sample…

Alcohol abuse has been described by college presidents as the number one problem on campus, and it is an important cause of death in young adults. How common is it? A survey of 10,904 randomly selected U.S. college students collected information on drinking behavior and alcohol-related problems. The researchers defined “frequent binge drinking” as having five or more drinks in a row three or more times in the past two weeks. According to this definition, 2486 students were classified as frequent binge drinkers. Construct and interpret a 99% confidence interval for the proportion of students who are classified as binge drinkers. (Use the four-step process.) In the normal condition, np is 8,418, which is greater than 10 so the normal condition is met. Is this statement true or false?
