Well, the average IQ in the world ranges from 86 - 120, you can take comfort in the fact that 112 is on the high end.Therefore, we can say that a 112 IQ is a good score.It shows you possess an above-average critical thinking skill or problem-solving ability., After 5 years, the child is administered an IQ test. We know that IQs are normally distributed with a mean of 100 and a standard deviation of 15. Suppose the IQs of the 20 children in the study result in a sample mean of 104.2. Use the model from part (d) to compute the probability of obtaining a sample mean of 104.2 or greater., A 107 IQ score is slightly above the average score of 100. This means that an individual with this score has a higher-than-average level of intelligence. They are likely to have better problem-solving abilities, a stronger grasp of abstract concepts, and a quicker learning speed compared to the average person., Statistics and Probability questions and answers. 1) IQ test scores are normally distributed with a mean of 104 and a standard deviation of 15. An individuals 10 score is found to be 111. Find the 2-score corresponding to this value Ans: Z-0.47 2) An airline knows from experience that the distribution of the number of suitcases that get lost ..., After 5 years, the child is administered an IQ test. We know that IQs are normally distributed with a mean of 100. If the IQs of the 20 children in the study result in a sample mean of 104.2, and a sample standard deviation of 14.7, is there evidence that the children have higher IQs? Use the a = 0.05 level of significance., A standard deviations is a measure of a data set's spread or variability. As mentioned above, scores mean different things based on the IQ test being used. The graph below shows the spread of scores for the popular Wechsler tests. The mean is 100 and the standard deviation of 15 means that 68% of test takers fall between a score of 85 and 115.
