Mit Vergnugen!
Thank you for making these videos. Such a great help! ❤
This is great ❤
AMAZING❤❤❤❤
THANK YOU
My problem is fully solved. Thanks.
How do I find SummationX Squared?
Clearily and understandable
I finally understand, thank you!
Very clear and helpful, thank you so much
ur a beast dawg, explained it hella well, btw where are you from cuz we got this course at york too so m j wondering if u got it from there
im gonna be binging your channel through my stats class
Would have been way easier to follow had you plugged in the actual numbers.
Hello sir, Why aren't you uploading more videos? The way you teach is really awesome, it is very easy to understand when you teach. Very calm and patient teacher you are.
Thank you Uma. I will add more videos. What would you like to see me cover? Perhaps I’ll be able to post that here
@@work4120Actually i have a Statistics University exam on 1st May(the coming Monday) and suprisingly your channel has almost all my course topics already been uploaded but i didn't find probability sums, if that is possible can you please upload probability sums here? I have some practice sums given by my professor but i am having a hard time to be able to solve them. If i mention those practice sums here, can you please upload a video of them, if that is possible?
Practice sums of probability: 1.(A) The weights of 10-year-old girls are known to be normally distributed with a mean of 70 pounds and a standard deviation of 13 pounds. Find the percentage of 10-year-old girls with weights between 60 and 90 pounds. 1.(B) Find the 60th percentile for the weight of 10-year-old girls given that the weight is normally distributed with a mean 70 pounds and a standard deviation of 13 pounds. ANSWERS: z = (-0.77 and 1.54); probability is 71.76. 2. Scores on a particular test are normally distributed with a standard deviation of 4 and a mean of 30. What is the probability of anyone scoring less than 40. ANSWERS: z = 2.5; p= 99.38. 3. Annual salaries for a large company are approximately normally distributed with a mean of $50,000 and a SD of $20,000. What percentage of company workers may under $40,000? ANSWERS: z = -0.5; p = 30.85%. 4. 1Q scores have a normal distribution with a mean of 100 and a standard deviation of 15. What percent of people have an IQ above 1207. ANSWERS: z = 1.33; p= (9.18%). 5. The amount of time a student taking statistics spends on studying for a test is normally distributed. If the average time spent studying is 12 hours and the standard deviation is 4 hours, what is the probability that a student will spend more than 8 hours studying? ANSWERS: z = 0.8413; p = 84.13% 6. Scores on a history test have average of 80 with standard deviation of 6. What is cut off score that encompasses the middle 75% of the distribution 7. The temperature is recorded at 60 airports in a region. The average temperature is 67 degrees Fahrenheit with standard deviation of 5 degrees. At what given temperature, will there will be a probability of temperature be recorded getting below 15% 8. A group of friends compares what they received while trick or treating. They find that the average number of pieces of candy received is 43, with standard deviation of 2. If a child has more than 32% probability of getting a candy, what is least amount of candy they require. So sorry sir to trouble you. But it will be very very helpful if you upload a video of these.
thanks boi
Great explanation,, I'm curious what is app/software you use for your black board?
🙈♥️👀 thankew sir
What does "below the mean" means? The x is given and standard deviation but the mean is not. I mean how to find that?
Thanks for this video man. It helped me figure out how to do my homework work…
this is the first time I don't see PEMDAS
Really helped. Thanks a lot
❤️
thanks!
How do you square ex?
Great explanation, thanks!
It is a poor presentation and not attractive.
If I had a nickle for every time I heard that
Easy to say.
Very well explained ,,, short , precise and detailed
Thanks so much for this tutorial! Much needed!!!
how to find the total frequency
Thankyou
What is Percentile rank of 3.0 ? Thank you
I think he just explained the equal to or less than using the percentile rank, so that would still be 3.5, I could be wrong tho..
@@Erica-yu6jw i think 3.0 = Percentile rank 76.78%. (20+1.5)/28*100 i’m not sure.
thanks this is helpful
Thank you for the video, can you help me how to prove that is unbiased in this question? Question: Compare the average height of employees in Google with the average height in the United States, do you think it is an unbiased estimate? If not, how to prove it is not mathced?
Thank you so much !
Thank you
Thank you so much for this.
Great!
Awesome thanks 😊
Very cool description
Wonderful description TY ❤❤👌👍👏👏
i have to give major props to you for your clear and concise explanation. The text I am using is not not very clear as to the distinction between percentile and percentile rank. Good teaching! Thank you!
I feel Your teaching process is really fantastic.
How would I do this from a histogram? I don't have the original data set just the histogram and I need to calculate sigma x
Finally, someone that is straight to the point and that isn't speedy Gonzales
Hi, how do you get the 100% result score on the frequency distribution table in getting the cf?
That was a really concise explanation. Thanks
best explanation on youtube
:) Thanks
Sound is terrible, too low.
