Unit 5 – BB1 – Ferret Out Silliness I’ve chosen a study that researches the relationship between attachment and sensory modulation in children. Their research question is‚ “Is the health of the attachment relationship in these children predictive of their sensory modulation function?” As a correlation study a non-experimental design was used. Participants were recruited using convenience sampling with a mean age of 51 months‚ including 38 girls and 30 boys. Measurements used; Attachment Q-Set

probability? CASE STUDY : 2 The price P per unit at which a company can sell all that it produces is given by the function P(x) = 300 — 4x. The cost function is c(x) = 500 + 28x where x is the number of units produced. Find x so that the profit is maximum. Question: 1) Find the value of x. 2) In using regression analysis for making predictions what are the assumptions involved. 3) What is a simple linear regression model? 4) What is a scatter diagram method?
