[J2 Maths PMCians]
What we did in 2 hours:
We finished our revision on Normal Distributions and Sample Mean Distributions. We applied our Normal Distributions techniques including direct probabilities and inverse-normal operations (do note how left-tailed or right-tailed GC operations affect inequalities!). Also, we applied linear combinations to situations involving multiple normal distributions.
On the Sample Mean Distribution side, we noted that presentation is key (approximately normal)! Otherwise, it would largely be another Normal Distribution question. Additionally, always be ready to identify the Expectation and Variance of any context, be it from a binomial distribution or a discrete random variable setup.
Hypothesis Testing revision this week, dont forget the GCs!
See You and Stay Healthy!
