It has been a while since my last post and many things have happened since then. For one, I decided to upgrade my laptop as I saw it fit for the direction I am moving towards particularly on data analytics. It's been almost 10 years since I bought "Julian", my first work laptop, and there were so many milestones that we shared together. I bought my first laptop during my second job in Taguig City. It served as an extension of myself as I work to earn for my family particularly in helping my siblings with their education as I am the eldest and breadwinner of the family.

Julian was my laptop when I finished my Master's degree at the Ateneo de Davao University where I also created the Programmable Logic Controller Trainer ...
In the following z-table, we are highlighting how to determine the area to the left of z = 2.34. Notice how we separated 2.34 into 2.3 and 0.04. Then, we look for 2.3 in the first column and 0.04 on the first row. The intersection of these two locations in the table will be the p-value to the left of z. This means that P(z < 2.34) = 0.99036. In the following z-table, we are highlighting how to determine the area to the left of z = -1.86. Notice how we separated -1.86 into -1.8 and 0.06. Then, we look for -1.8 in the first column and 0.06 on the first row. The intersection of these two locations in the table will be the p-value to the left of z. This means that P(z < -1.86) = 0.03144. You can find an unblurry version of the z-table at https://www.math.arizona.edu/~rsims/ma464/standardnormaltable.pdf.
