LET'S DO THIS! 1. If scores are normally distributed with a mean of 25 and a standard deviation of 7-5, what percent of the scores is: a. Equal to 35? b. Greater than 40? c. Between 28 and 42? 2. There are 1575 incoming freshmen students at a certain university who took the entrance examination. Assuming that the scores are normally distributed with a mean of 98 and a standard deviation of 12, find how many have an 1Q of: a. Lower than 90. b. Greater than 110. c. Between 75 and 110. 3. In a modular class on Mathematics in the Modern World, it was found out that the students could complete the course in an average of 125 hours with a standard deviation of 12 hours. Assuming that the data are normally distributed, what is the probability that a student selected at random will complete his/her module in at least 175 hours? If there are 200 students enrolled in the program, how many of them could finish the course in not more than 150 hours? 4. Describe a normal distribution. 5. Identify the characteristics of a normal distribution and define each
