@staassis unfortunately I don't know levene's test, I will google it and see if I can figure it out.
@GretaGarbo The standard deviations are not the same, but I can't really tell if they are similar. is there a rule for it? or agreed upon approximation?
Should I used the TS-pooled or TS-unpooled to calculate the below question;
Two competing coffee shops wanted to know how satisfied their customers were with their drink choices (on a scale of 1 to 7, where 1 is very unsatisfied and 7 is very satisfied). They’re assuming that there is some...
Odd enough when I tried he below it gave me a right answer;
P(A and B) = P(X =10) = 0.05
P(B)= P(X = 0.24+0.14+0.11+0.05) = 0.54
0.5/0.54 = 0.09259 ~ 0.09
It doesn't make sense from the formula since I assumed the intersection is just the P(X =10), what am I missing
Thank @obh for your reply. I am fairly new to statistics so excuse my naivety;
to make sure I understand you right.
P(A|B) would be = P(A and B)/ P(B) = P(X= commutative 7) / (P(X= commutative 10) = 0.7/ 1 ?
I think I am still not getting it.
Hello I am new to statistics and I am not familiar with the R lab. I was trying to solve to calculate the least squares regression and I am not able to understand the code below. Can you help me please
Construct the least squares regression line based in the following output:
