This activity will help you distinguish between a sample statistic and a population parameter Part I Proportions from Random Samples Vary Imagine a small college with only 200 students, and suppose that 60% of these students are eligible for financial aid. What is the population? What is the variable? What is the population proportion? Note: Populations are usually much larger than 200 people. Also, in real situations, we do not know the population proportion. We are using a simplified situation...

Your local Target store is interested to know how much money, on average, their customers spend each visit in the housewares department. They go back through their records and draw a sample of 450 people and calculate each customer's average spending on housewares. a) Identify the population, sample, parameter, statistic and variable for this example. b) Describe a situation in which you would calculate a parameter rather than a statistic . For the 1,000 samples, the following is a breakdown of how much...

2.1.42 In order to investigate how many hours a day students at their school tend to spend on course work outside of regularly scheduled class time, a statistics student takes a random sample of 150 students from their school by randomly choosing names from a list of all full-time students at their school that semester. The student finds that the average reported daily study hours among the 150 students is 2.23 hours. Identify the...
