Reflection question 21th, July, 2021 I completed writing unit 6 learning journal and submitted, opened the material for unit 6 and read through to be sure of what to do during week 7 and to plan for my class well. 22nd July, 2021 I started reading chapter 6 (The Normal Random Variable) starting with section 6.1 (Student Learning Objective) and 6.2 (The Normal Random Variable). I didn’t find difficult in reading these chapters at all. 23th July, 2021 Proceeded to read sections 6.2.1(The Normal Distribution) and 6.2.2 (The Standard Normal Distribution) of the textbook. found the content not so easy to understand. 24th July, 2021 I read section 6.2.3 (Computing Percentiles) and 6.2.4 (Outliers and the Normal Distribution) and posted in the discussion forum 25th July, 2021 I read section 6.3 (Approximation of the Binomial Distribution), section 6.3.1 (Approximate Binomial Probabilities and Percentiles), section 6.3.2 (Continuity Corrections) practiced through section 6.4 (Solved Exercises), attempted the self-quiz, commented and rated three posts on the discussion forum and partially answered the written assignment unit 4. there were some hardships in the self-quiz but later overcame them. 26th July, 2021 I completed the written assignment unit 5 and submitted for grading. I managed to complete all my assignments in time following the advice from my instructor 2. Vocabulary and R functions. a) Normal distribution is a probability density function for a continuous random variable in a system and it is bell shaped (Byju’s, n.d). b) pnorm() is a function for distribution 3. Task

standard deviation = 2 mean = 10 In this case, the highest is 99% and the lowest is 1%. so I tell them to calculate it like this;

the lowest 1% of the number > qnorm(.01,10,2) [1] 5.347304 the highest 1% of the number > qnorm(.99,10,2) [1] 14.6527 Reference: Byju’s. (n.d). Normal distribution. https://byju’s.com/maths/normal-dostribution/...
