detailed solution

A. True or False. Write the word TRUE if the statement is correct and FALSE, if the statement is incorrect 1. The total area of the normal curve is 1 2. Normal probability distribution is used to determine the probabilities of a discrete random variable 3. The mean, median and mode have the same value. 4. The distance of the number in the horizontal line or the x-axis should always proportion. 5 The normal probability distribution has a mean p = 1 and standard deviation o = 0, it is called as standard normal distribution. B. Read the following problems carefully. Use empirical rule to answer each question. 1. IQ scores of the ALS students in the Division of Quezon are normally distributed with a mean of 110 and a standard deviation of 10. What percent of the distribution falls within the IQ scores of 100 to 130? 2. A normal distribution of data with the mean of 78 and standard deviation of 9. What percentage of the data would measure 87
