QUAFor Numbers 11 to 15: To determine the efficacy and lethal dosage of cardiac relaxants, anesthetizedguinea pigs are infused with a drug (A, B, C, or D) until death occurs. Each drug was randomlyassigned to ten guinea pigs, and the total dosage required for death of each guinea pig wasrecorded (smaller lethal doses are considered more effective).

In a study, the effects of the mane of a male lion as a signal of quality to mates and rivals was explored. Four life-sized dummies of male lions provided a tool for testing female response to the unfamiliar lions whose manes varied by length (long or short) and color (blonde or dark). The female lions were observed to see whether they approached each of the four life-sized dummies. Complete parts (a) through (e) below. a. Identify the experimental units. Choose the correct answer below. The female lions The male dummies The mane colors The mane lengths Part 2 b. Identify the response variable. Choose the correct answer below. A. Whether or not (yes or no) the mane length affected how the female lions reacted to a male dummy. B. Whether or not (yes or no) the female lions approached the same dummies. C. Whether or not (yes or no) the female lions approached a male dummy. D. Whether or not…
A pharmaceutical company tested the impact of four cholesterol-reducing medications (denoted A, B, C and D) on people at high risk of heart attack. For this clinical trial 20 volunteers with LDL (bad) cholesterol levels of 140 mg/dl were randomly assigned to one of the four medications. The subjects were instructed to take one tablet per day for a period of three months after which their LDL levels were again measured. Below are the amounts (in mg/dl) by which the LDL levels decreased after the three month trial. | Medication A | Medication B | Medication C Medication D 31 30 31 30 32 31.5 32 35 29 30.5 29.75 27 33 30.5 31.75 31 29 31.5 33 29 (a) Write an appropriate statistical model (to represent the responses using an appro- priate equation) to describe the above data.

Eyeglassomatic manufactures eyeglasses for different retailers. They test to see how many defective lenses they made in a given time period and found that 10% of all lenses had defects of some type. Looking at the type of defects, they found in a three-month time period that out of 34,024 defective lenses, 5840 were due to scratches. Are there more defects from scratches than from all other causes? State the Type I and Type II errors in this case.State the Type I error. Concluding that the proportion of defects from scratches is 10%, when in reality it is less than 10%. Concluding that the proportion of defects from scratches is 10%, when in reality it is higher than 10%. Concluding that the proportion of defects from scratches is less than 10%, when the proportion is actually 10%. Concluding that the proportion of defects from scratches is higher than 10%, when the proportion is actually 10%. State the Type II error. Concluding that the proportion of defects from scratches is…

A particular moth can infest avocado trees and potentially damage the avocado fruit. A farmer plans to investigate the number of damaged avocado fruit on moth-infested avocado trees of a certain variety. A recent article states that the population distribution of the number of damaged avocado fruit on moth-infested avocado trees of this variety is symmetric but not mound-shaped with mean μ =59 and standard deviation σ = 24 . (a) Compare the shapes of the sampling distributions of the sample mean number of damaged avocado fruit for random samples of 6 moth-infested trees and for random samples of 90 moth-infested trees from the population. (b) Which of the following would be less likely to obtain from the population? • A random sample of 36 moth-infested avocado trees…

What is a unique advantage of the Latin Square design? It reduces the carryover effect while maximizing the strength of the IV manipulation. The Latin Square design uses multiple langauges. It counterbalances while reducing the number of groups/people needed to control for order effects. It is useful in an independent groups designs when matching participants on the dependent variable.

At a factory, certain metal components are manufactured on two different machines (A and B). The quality control manager suspects that machine B produces components that are stronger and more durable than those produced by machine A. To test this, he randomly selects twelve components from each machine. The components are put through a wear-testing machine and the amount of wear (in mm) is recorded 1. a. H1: Pd 0 c. H1: HA HB e.
