Great teacher mam🎉🎉🎉
@@katikireddymadhavidevi4572 thank you so much for the wonderful comment!! Really means a lot!! 😊😊👍👍👍
Variance=27.428Standard deviation= 5.237
That's the correct answer!! Great going!! 👏👏👏👏👏👏
@@EnjoyMath thankyou ❤️
Variance 28.75SD5.34
Almost correct!! Good job...👍👍Mean = 28(xi- mean)²=192Variance= 192/7= 27.4286SD= 5.2372Pls check and let me know...
sigma ans is (27.428) and standard dev is (5.2371
@@makkashivani7448 excellent!! Correct answer!! 👏👏👏👏👏👏
Mam please 9th ko pdhaiye
channel ka scope abhi 10th,11 th,12th hai, 9 th ka bhi start karun toh channel ka content too diverse ho jayega...phir mujhe Naya channel hi start karna padega ..I will think about it....but thank you so very much for your support 🙏🙏🙏
