A developmental psychologist prepares a video tape which demonstrates the “conservation of matter”. She selects 8 young children from a day care and first tests them on this type of problem (that matter is the same volume regardless of shape) and records the number of correct responses. She then shows the video tape and re-measures their ability to solve these problems. Below are the results:
# correct           # correct
Child       before tape           after tape
1       3               8
2       0               6
3       6               4
4       2               8
5       9               10
6       8               6
7       6               2
8       5               10

Two-way ANOVA (8 pts) Research Scenario: A developmental psychologist is looking into the effects of play group size on empathy and whether this differs by age. She has two age groups – four year olds and eight year olds. Each of those age groups is split into three separate groups for an entire semester during structured free time: play alone (n = 8 per age group), dyads (n = 8 per age group), or groups of 4 (n = 8...

Consider a game in which, simultaneously, player 1 selects a number x ∈ [0, 8] and player 2 selects a number y ∈ [0, 8]. The payoffs are given by: u1(x, y) = 2xy − 8x − x 2 u2(x, y) = 4xy − y 2 (a) Calculate and graph the best responses for each player. (b) What strategies are never played? (c) Find all Nash equilibriums? (d) What is the preferred equilibrium in society? (e) How would we classify...

The psychologist gathers a random sample of 17 SI scores of smokers and finds that their mean is 126 and their standard deviation is 34 . Assume that the population of SI scores of smokers is normally distributed with mean μ . Based on the sample,...
