31.Does the regression equation account for a significant portion of the variance in exclusion judgments? Use α = .01. Enter the test statistic, critical value, and decision as part of your answer. Test statistic = ? Critical value = ? Do you reject or retain the null hypothesis that the slope is not different from zero? (Enter "Reject" or "Retain"): ?
Addition Rule of Probability
It simply refers to the likelihood of an event taking place whenever the occurrence of an event is uncertain. The probability of a single event can be calculated by dividing the number of successful trials of that event by the total number of trials.
Expected Value
When a large number of trials are performed for any random variable ‘X’, the predicted result is most likely the mean of all the outcomes for the random variable and it is known as expected value also known as expectation. The expected value, also known as the expectation, is denoted by: E(X).
Probability Distributions
Understanding probability is necessary to know the probability distributions. In statistics, probability is how the uncertainty of an event is measured. This event can be anything. The most common examples include tossing a coin, rolling a die, or choosing a card. Each of these events has multiple possibilities. Every such possibility is measured with the help of probability. To be more precise, the probability is used for calculating the occurrence of events that may or may not happen. Probability does not give sure results. Unless the probability of any event is 1, the different outcomes may or may not happen in real life, regardless of how less or how more their probability is.
Basic Probability
The simple definition of probability it is a chance of the occurrence of an event. It is defined in numerical form and the probability value is between 0 to 1. The probability value 0 indicates that there is no chance of that event occurring and the probability value 1 indicates that the event will occur. Sum of the probability value must be 1. The probability value is never a negative number. If it happens, then recheck the calculation.
(For Questions 28 - 31). Moral judgments about a harmful behavior are expected to be associated with one’s ability to recognize how hurt the victim of the harmful behavior is. To test this a replication of the Malti and colleagues (2012) was attempted. Researchers asked 12- and 15-year-olds whether they thought it was okay to exclude a Serbian peer from going to a soccer match (1 = really not okay, 7 = really okay) and how they thought the Serbian peer would feel if he/she was not invited to the soccer match (1= very bad, 7 = very good). The results for 12 of these adolescents are below:
