Activity 1. TRUE or FALSE Direction: Read and analyze the statements below. Write TRUE if the statement is correct, otherwise write FALSE. _1. Nearly the entire distribution (about 99.7% of the area under the curve) falls within 2 standard deviations of the mean. 2. The standard score is obtained by dividing the difference of the raw score and the mean to the standard deviation of a given normally distributed variable. 3. If u = 95.5, o=10, and X = 115.5, then the z-score is 2. _4. A distribution which is not normal can be normalized by changing all the scores in the distribution into z-scores. 5. All z-scores to the right side of the curve are negative while those to the left are positive. 1
