at 07:58 the equation will be I think P(X^2 is greater than 6) is less than 10% as per the chi-square distribution table

[umr]

I still can't make out the end part of the video..

[noreallycaresabout]

Thanks a ton
I stink at math, but I was still able to understand this

[shubhatal]

Shouldn't the p value be less than 10% for getting greater than 10%

[jaycee]

Why are we allowed to obtain the p-value from a chi-square distribution?

[richashrivastava]

I did not get why the null hypothesis is not rejected.

[yousefalkhaldi]

"it might have just gotten more Ds"

[mesiintel]

How did you get the actual #? I understand everything else, just not sure how you got that number.

[Maria]

We can only reject the Null hypithesis. Are you sure we can accept something?? Or we can test for rejection or not rejection?

[soltangaliyevassanali]

No, it doesn't make any sense for me till there will be explanation why chi squared has exactly this formula.

[enormousmaggot]

Why not, instead of continuously adding new videos, add practice activities for existing courses?

If I wanted to watch YouTube vids there are plenty of more engaging channels :(
