WebSolution: The z score for the given data is, z= (85-70)/12=1.25. From the z score table, the fraction of the data within this score is 0.8944. This means 89.44 % of the students are within the test scores of 85 and hence the percentage of students who are above the test scores of 85 = (100-89.44)% = 10.56 %. is tammy and waka still together 2022WebNormal distribution is a continuous probability distribution.
