Research Design (Assignment 2) I will be conducting a study using a true experimental research design in order to investigate the effects of marijuana use on an individual’s problem solving ability. Marijuana use is the independent variable which is operationally defined as consumption in the form of smoking 0.5 grams of cannabis in a marijuana cigarette. Problem solving abilities is the dependent variable which is operationally defined as the total score on various math problems as well as time

feet of the home? Does having a house with more square feet mean that the price of the home will increase? Well my fiancé and I are looking to buy a home and have come to the conclusion of five factors that we think are the most important. Using statistics, we will narrow our search down from 108 homes to only a few homes. The first thing, we need to discuss is the dependent and independent variables. Since we are most concerned with the price of the home and how other factors affect it, we will

Portfolio Analytics 1. Introduction: To analyze our portfolio and determine its exposure to risk factors, we assumed that: Rit+1=a+bi,1F1t+bi,2F2t+…+bi,nFnt+eit+1 First, we calculated z-score for logarithm of b_p and logarithm of cap to determine sensitivities for stock-specific factors. After we got all 13 sensitivities, we did a weighted regression of the 13 sensitivities against the 1000 stock’s forward return in 60 periods, respectively. For each period, we got 13 coefficients

Problem 1 A random sample of 16 adult males is about to get into an elevator which has a weight capacity of 2900 lbs. The adult male weight follows the normal distribution with a mean of 170 lbs and a standard deviation of 15 lbs. (a) What is the probability that the total weight for this sample of 16 adult males will exceed 2900 lbs? Hint: This is the same as calculating the probability that the average weight for a random sample of 16 exceeds 2900/16. (b) Will the probability
