    It's very good lecture but it would be much better if you put the series of all lectures because we face a lot of difficulty in finding them

    I am 95% confident that your statistics class covered at least 95% requirements for quality control of business operations (manufacturing, financial, legal and risk management). --- you are a great teacher.

    He is an amazing teacher. He makes it so simple and easy to understand and leaves the JARGON outside the door. I managed a B in my elementary stat class because of him. I was lost in my stat class because of Covid-19 all classes went online, and there was no way I could understand probability by reading a book. I stumbled on these videos and decided to purchase a 1 month package $ 20 and it was FULLY worth it. Thank you.

    Almost all distributions convert into a normal distribution as n ( number of samples) is very large (its better to say n -> infinity) .
    This is the essence of the Central Limit Theorem.

    for a 1 tail test, at 0.90 confidence level, shouldn't your degree of freedom be 1.645 instead of 1.28?

  • @dannyassuncion8714

    Very nice explanation.... how about this.
    In a class at the University of Florida, 49 students are given a
    blind taste test comparing Coke and Pepsi. Approximately half
    of the subjects are randomly chosen to receive Coke first and
    the rest randomly receive Pepsi first. Why? Coke was
    preferred 29 times.
    1. Is there evidence to suggest that students have a taste
    preference between Coke or Pepsi? Carry out a hypothesis
    test by completing the following steps, and using a level of
    significance of 0.05:
    (a) State the null and alternative hypotheses
    (b) Calculate the test statistic
    (c) Calculate the p-value
    (d) State the conclusion

    Allah is the Light of the heavens and the earth. The parable of His Light is as a niche and within it a lamp: the lamp is in a glass, the glass as it were a star Durriyyun, lit from a blessed tree, an olive, neither of the east nor of the west, whose oil would almost glow forth, though no fire touched it.
    The exact translation of the saying is, “I bear witness that there is no deity but Allah, and I bear witness that Muhammad is the messenger of Allah.
