Subjects wererandomly assigned to each of three groups to do a stressful task alone (the control group), with agood friend present, or with their dog present. The subject’s mean heart rate (in beats perminutes) during the task is one measure of the effect of stress. The data has the mean heart ratesduring stress with a pet (P), with a friend (F) and for the control group (C).Result: The

functions: Inflating a balloon The change in the volume of a constantly inflated / deflated balloon depends on thechange in its radius which changes as a function of time (Figure 10). Figure 10: Inflating a balloonQuestion: What is the change in volume of the balloon as a function of the incoming air flowq(t)?Assuming a spherical balloon, its volume V is 4 𝑉 = 𝜋 𝑟3 3If the radius changes with time due to the incoming air rate, q(t), then according to the ChainRule 𝑑𝑉 𝑑𝑉 𝑑𝑟 𝑑𝑞

: Yij = β0j + β1j X1ij + β2j X2ij + β3j X3ij + β4j X4ij + ijwhere β0j is the intercept for the level 1 equation and β1j , β2j , β3j , β4j are the level 1 coeffi-cients of each X. Also, ij represents the level 1 random effect. The level 1 coefficients andintercept become the outcome variables for the level 2 variables. The level 2 model is βqj = γq0 + γq1 W1j + γq2 W2j + γq3 W3j + γq4 W4j + uqjwhere γqj , q = 0..4, are the level 2 coefficients of each W and uij represents the level 2random effect.The first step in the analysis is to run the empty or unconditional model (Model 1) and com-pute the intraclass correlation coefficient (ICC) in order to compute the proportion of the totalvariance in each class.

Several students attended the organized events and interacted with the engineers toform a better idea about the engineering profession. Many of the engineers shared theireducational experiences, gave insightful advice and tips on time management and priorities. Thecasual interaction with the visiting engineers after the Q&A sessions typically received highmarks from the
