In Foundations of Math 11 in the statistics unit the class learnt how to understand a normal distribution curve which is used for many things. The normal distribution curve or bell curve can be used to find percentages, numbers, etc. If you have a mean or an average number you can put that in the middle and have standard deviations that are a specific number off of the mean. In the bell curve there is the mean in the middle with three standard deviations on each side of it, the right side having the standard deviations add from the mean. Then the left standard deviations subtract from the mean, there are percentages in the sections between the standard deviations. The natural distribution curve can be used for businesses for finding what size shoe to buy more than another or anything else. A formula is used to find an answer you are missing, the formula is z=(x–μ)/σ. I feel I understand this topic, but still could go through and practice more. A challenge I had in this unit was with the confidence intervals and margin of error lessons. I felt it was challenging trying to remember the way to get the confidence interval, but after a little bit I got better at it. The way I overcame this was doing many questions involving it and getting a hang of it. One thing I want to work on for the next unit is trying to studying more during my free time and go through questions that I feel are harder. Lastly, In class I will get homework done and if I have free time I will try and go through extra questions to see if I have the hang of it.
