Question: Children as young as 2 years of age, upon seeing an object placed under a pillow in a familiar setting at home, will understand to look for it after an interval of tiMeand be able to find it. Investigators believe this capability will be less pronounced in a laboratory situation, where the child is away from the familiar setting of home. Let π denote the proportion of 2-year-olds that have this understanding in the home situation, and suppose that π = 0.35. The investigators wish to determine whether the proportion that remembers is less when the child is away from home. *What is the appropriate null hypothesis and the appropriate alternative hypothesis? *Distinguish between a Type I and a Type II error in this context.
