What is log base 2 of 2
1
What else can effect correlation
Third variable
For H0, what do you say if you have worked out the prob compared to where they give you prob
If you have worked out prob then say binomial is suitable if not state the specific distribution with n and p
etan(incoming) =
tan outgoing
For expected values they give you should you use their dp or exact values
Their decimal places
What does a smooth wall mean
Momentum acts parallel
What do you do with p value for two tail if only one side calc
Double it
How can you show cosh tends to infinity
Put it into e
When can you use chain rule
Only when you divide by a constant ( not like x ) original thing has to be linear
Important FORMULA
Quadratic formula
When can you not integrate using normal
When it is r+10 + dt as has to be times dt
When something is tending to infinity
Divide by x or x squared…
Integrate ln x
Parts
Can you integrate circles
Yes
What do you need to remember to do for inverse
Divide by determinent
Special thing about cos
remember that cos of -pie = -1 and cos of pieie = -1 cos can be neg or pos so if you want first time, sometimes go for neg
log(2)-1
1/log2
H0 two way
No association so if it exceeds critical value then there is an assocation
H0 gof
Suitable so if exceeds critical value then not suitable
Do you need continuouty correction for normal aprox of binomial mean
No as it is mean
Why do you take away 1 dof
base constraint for table is all totals add to 173
How do you show 2 lines are on same plane
Show they intersect at a point
Solve two and
Check in the third
When is an integral improper
Wehn one limited is plus minus infiniuty or undefined at any point
