[babasprincess]

Mery 23 ko papers hain .. ye topics bhut zrurt hain .. Thanks God now all concepts cleared😍

[divyam]

In the last question i believe h1 should not be accepted either its because that test is exceptional and we have to take the negative z value in account we cant use modulus. And therefore the answer should be tubes have lower lifetime than 1600 hrs

Thank you so much sir.
Wish everyone meet a teacher like you.
Love from nepal❤️

It was really very helpful sir i already watched 10 videos before watching this but didnt undeestand anything but after watching your video my concepts are clear now

[shardamakwana]

Sir ek question tha ki presise and acuracy se related jab apn inhe solve krte h to mean ka konsa formula laghta hai like question ye h ki true value ko hai wo 3 hai
Ramesh 2.80 / 3
Suresh 2.91 / 2.90
Rohit 3.01 / 2.99
Rakesh 2.90 / 3.10
Sir issme mean nikalna ho to kaunsa formula lagega presise acuracy sir pls reply

Hi Gaurav, thank you so much for this video. One thing is not clear- in the second example we found the |Z| = 4, so it is falling on the right side rejection area. For this we rejected the null hypothesis but the alternate hypothesis which claims about average life time greater than 1600 hours should also be rejected. This is because the probability of 1600 hours itself is very small, any value greater than 1600 will have far smaller probability. In the curve it will be further right in the rejection area. I think either both of the hypothesis should be rejected or the alternate hypothesis should say - average of population is less than 1600 hours. Please clarify.

[shantanushit]

sir huge respect just wanted to know want to solve a lot of questions regarding prob and statistics like this regarding confidence level hypothesis mean variance which book would be best as for operational management pls guide sir thnqu

[pabitralamichhane]

Very effective video 😘Thank you so much sir 🙏

[sudiptiwari]

sir, if calculated z is -4, it means that it falls in left side rejection region i.e. the alternate hypothesis x̄ < μ is correct.. but the question is asking alternate hypothesis x̄ > μ...so what is the solution?

[sapnagupta]

Sir bhut hi achaa pdhate ho ap...apke videos dekh k chapter samjh aaya

[sharmatheakshat]

Sir I have just one request from you
Please🙏upload videos on types of sampling like simple random sampling, stratified random sampling etc
It will be very helpful for us ☺️
