Concept explainers

Counting Principles

In statistics, the counting principle can be said to be the concept in which the quantity of an item is determined. There can be a single item, or a group of items, or items that are related to each other. In every possible set of items, the quantity of the possible item groups or their sorting measures can be determined with counting principles.

A researcher studies the effects of guilt on memory. First, subjects perform a very boring task for one hour. Then each subject is instructed to tell the next subject either (a) that the experiment took one hour and they found it very boring, or (b) that the experiment took one hour and was very interesting. After that, each subject is asked to study a list of words and are tested on memory for the list. 30 subjects are randomly assigned to one of the two conditions. In order to see whether the experimental manipulation has any effect on memory, which would be the proper statistical test? A)a related sample t-test-test   B)an independent sample t-test   C)a z test   D)a one sample t

250 adults are practicing every day before taking part in a high-stakes children's game. The game requires them carefully to remove a shape- either a star or an umbrella-from a sugar wafer. 30% of those who choose stars on a given day will switch to umbrellas the next day, and 20% of those who choose umbrellas on a given day will switch to stars the next day. (a) If 150 contestants practice with stars today, how many will practice with umbrellas tomorrow? (b) If the actual game is held a long time from now, what proportion of contestants do we expect will be practicing with stars each day close to then?
