State the null hypothesis H 0 and alternative hypothesis H a Ha in each of the following cases. (a) A university gives credit in first-year calculus to students who pass a placement test. The mathematics department wants to know if students who get credit in this way differ in their success with second-year calculus. Scores in second-year calculus are scaled so the average each year is equivalent to a 79. This year 21 students who took second-year calculus passed the...

1. Does reading on a light-emitting e-reader at bedtime increase how long it takes to fall asleep? A sample of 12 healthy adults slept in the lab on two different nights. In random order, subjects read for 30 minutes in a print book one night and with a light-emitting e-reader the other night. Scalp electrodes were used to measure how long (in minutes) it took subjects to reach a deep sleep stage. The researchers compared the difference in the amount...

It is believed that students who begin studying for final exams a week before the test score differently than students who wait until the night before. Suppose you want to test the hypothesis that students who study one week before score different from students who study the night before. A hypothesis test for two independent samples is run based on your data and a p-value is...

3. Asset management ratios Aa Aa E Asset management ratios are used to measure how effectively a firm manages its assets, by relating the amount a firm has invested in a particular type of asset (or group of assets) to the amount of revenues the asset is generating. Examples of asset management ratios include the average collection period (also called the days sales outstanding ratio), the inventory turnover ratio, the fixed asset turnover ratio, and the total asset turnover ratio....
