Very helpful! thank you

[@korjedeeachira6528]

Hello sir, should the number on (1-p) be (1-0.2)?

[@-pipsy-]

hi i have checked and it supposed to be 1-0.2, however when you convert the decimal places, you will be getting 2.179 which can convert to 2.18

@@-pipsy- thanks 🙏

[@shwetankallphotossingh6813]

1-0.984= .0.0146. 0.0416 is wrong

[@joshemman]

Nice catch. Thanks.

[@ivywong378]

Why do we look at 2.1 under 0.08? I am not sure why 0.08., thank you!

[@joshemman]

2.18 = 2.1 + 0.08

[@MpenduloMashego-zn3ws]

why did that 20% change to 0.20 when writing the null and alternative hypothesis

[@joshemman]

20% = 0.20

[@jmcarino6339]

where did he get the 0.0290? 1:19

[@joshemman]

At 1:19, 0.0290 is what you obtain when you evaluate the denominator.

​@@joshemmani substracted 1-0.9845 and its 0.0146 and not 0.0416 how was that

[@joshemman]

@@jmcarino6339 You're right. That was a transposition error.

[@iu.jieuni9166]

why 0.9854 is not the p-value? why do we need to subtract it from 1 first?

[@vipkosters6410]

Cause we look at a right sided tail. If you want to look at right sides values always 1-…, if you look at a left tail then you don’t need to substract it

[@LAKSHAYANAND-k8k]

P value is 0.0146... Please make that correction

[@FRAMEDWORLD960]

the p is 0.2 how com you use 0.8 instead of 0.2

[@joshemman]

You're right. There is a typo in the denominator at 1:08. The answer is computed using 0.2 however. Thanks for pointing it out.

great video omg thanks for saving me in stats

[@roshana4430]

1-0.9854= 0.0146
