hi sir sorry to disturb you but in the exam around how many practicals would you have to remember for enzymes, plants circuit fuels and diffusion thanks
@@btecappliedsciencehelp and sir is it one of each practical around how many are there on each for example 1 for enzyme one for plant one for circuit and one for fuels and one for diffusion
@@mohamudh7767 Hi Mohamud. Its impossible to predict what practicals will come up on the exam. Energy from fuels is a popular one. A colleague at work reckons a diffusion one is likely. Just be safe and be familiar with them all.
You say we are only interested in the 5% probability column but you don’t say why. Is it always the middle column or something? It also doesn’t explain why the degrees of freedom is number of measurements - 2… like is it always -2?
The degrees of freedom depends on how many samples you have in your experiment e.g if you are investigating 5 different alcohols then the number of samples you have is 5 so your degrees of freedom would be 4
And we use the 5% probability because when you use that you are saying that your results/ experiment is 95% accurate/ correct and that there is only a 5% chance in error or that it is 5% incorrect if that makes sense
@@araiyahs2427 Thank you so much. I literally retake my exam in 3 hours haha. Do you know if the 5% probability thing will be the same for every question? Will there always be a columb that’s 95% accurate?
I hope I never do the T-test in my life, if it comes up on fridays exam I will simply fade away.

it came up 🕺🏽🕺🏽🕺🏽🕺🏽
did you cope with it and the rest of the paper?
yeah it was okay overall but I got these '< >' mixed up for one of the questions, so I think the answer was meant to be rejected instead of accepted
@@jill4966 i got 0.16
@@joel0142 was that for the 6 marker one or the 2 marker? if it was the 2 marker one then I defo did that wrong 🥲
@@jill4966 6 marker
2 marker was 28- critical value
The criticle value really confused me
Why did the T TEST COME IN THE EXAM NAHH BROO
how did you find it 😭
@@jill4966 I lost those 6 marks for sure and the other connecting questions to t-test..
@@YoshiroWendy at least you didn't fade away ahahah
@@jill4966 😂
It was on the paper 2024 :(
Oh dear, I have it tomorrow :(
how have u already done the paper?
anymore clues?
Cheers g
Nah cmon man it came up in the exam. Ur lucky I don’t know where u live
in the question you were given the values of n, the means and the standard deviations. All you had to do was put them in the equation.
@@btecappliedsciencehelp I’m only joking the question wasn’t that bad
blimey, I was terrified you'd come round and kick my arse!
@@btecappliedsciencehelp what was t value for 6 marker?]
Oh nah I'm cooked
