Homework: Homework #4 Save Score: 0 of 1 pt 5 of 13 (2 complete) 8.1.13 HW Score: 10.26% Question: Determine which of the following studies would be tested with a test for independent means. A researcher measures work quality for 21 employees before and after taking a one-hour break. A researcher randomly assigns a group of 23 students to take the class and another group of students to not take the class, and then measures the efficiency of each individual. A researcher measures satisfaction in 16 employees before and after receiving a raise. A researcher compares the heart rate of 16 individuals who have been taking a particular drug to the heart rate of 51 other individuals who have not been taking the drug. Select all that apply: Study (6) Study (6) Study (6) Study (6)

Step 1
The first study involves measuring work quality before and after taking a break. This study would not be tested with a test for independent means because the same group of employees is being measured twice. Therefore, this study does not apply. Show more…

In a recent study on world happiness, participants were asked to evaluate their current lives on a scale from 0 to 10, where 0 represents the worst possible life and 10 represents the best possible life. The responses were normally distributed, with a mean of 4.8 and a standard deviation of 2.5. Answer parts (a)-(d) below. (a) Find the probability that a randomly selected study participant's response was less than 4. The probability that a randomly selected study participant's response was less than 4 is [ ] (Round to four decimal places as needed.)

Suppose that a drug is administered to a person in a single dose, and assume that the drug does not accumulate in body tissue, but is excreted through urine. Denote the amount of drug in the body at time t by x1(t) and in the urine at time t by x2(t). If x1(0) = 5 mg and x2(0) = 0, find x1(t) and x2(t) if dx1/dt = -0.1x1. Based on the given information, the equation dx1/dt + dx2/dt = 0 must be satisfied. Find x1(t) and x2(t). x1(t) = x2(t) = (Type expressions using t as the variable. Use integers or decimals for any numbers in the expressions.)
