Sample Proportions

[rileyregan]

Once again I had to find a smaller channel that actually does a good job of you. I hate that all these lazy professors love Khan Academy....they have 3 10 minute videos on this and you taught me better in 3 minutes

[howtodoit]

Wow pretty descent content. Better than my prof who just complicates simple stuff! Thank you!! You got a new sub

[Proxyincognito]

13 year old video and still the best explanation i encountered.

Thank you! Have an exam tomorrow and i missed this day in class. Great quick summing up, can do my sample problems to study by from this.

better video than popular youtube channel like khan academy.

[madisonhultman]

Wow you have idea how much this helped

[roseb]

actually can you please go into the details of this equation I was always confused what does the stadard deviation and variance of a proportion mean and how this formula is derived

[calmtune]

Why can't we take standard deviation of proportion in the normal way as standard deviation of mean

[annmargaretbalajadia]

where did the probabilities written in the graph came from? hope u see this, thank you

[riesakamoto]

at 2:03 - "is the distribution approximately normal", how come 0.15 is used as P? I thought that's the calculation we got as P hat (sample proportion)...

Should be np > 10 and n(1-p) > 10

[artfulflower]

Shouldn't p represent 0.05 and not 0.15? Where did you get the 0.15 from?
