How to write the discrete uniform distribution in function form

P(X=x) = a for Inequality of domain

table for discrete uniform distribution [done]

done

Comment on the suitability

comparision of model’s prediction to actual value suggests good or not good

Refinement to a discrete uniform distribution for cloud cover

reason (varies with location and month) so non-uniform

Explainatory variable

independent variable

Response Variable

Dependent variable

How to state with a reason which is the explainatory variable

x will be the explainatory variable because it affects y

What words must you not use when talking about the explainatory variable in relation to the response variable

CAUSES or EXPLAINS no causation

How to Interpret a gradient of a regression equation

every UNIT rise in BLAH results in a (CHANGE) in blip of GRADIENT VALUE (CONTEXT!!!)

State assumptions that BLAH needs to make to use her binomial model

Binomial conditions hidden in CONTEXT

How to find the probability of the first success being after m trials from a binomial distribution of success of the successes in n trials

(probability of failure)^(n-1)(probability of success)

If two values from outside the IQR have moved to inside the IQR but above Q₁ which two values will change on a boxplot and why

Median and Q3 because there are more values below (VALUE OF Median) than below

Given a normal model, a sample of n and starting with X > a how do you find the probability that NONE of the sample will have X < b (b>a)

Find 1 - P( a < X < b)/P(X > a) and put to the power of n g idk why not 1-p then divide?

Given a normal model, sample where n have (X > a) and m have no data, what is the probability that none of the sample will have (X < b)

(1 - P(a<X<b)/P(x>a))to the power n x P(X>b)to the power m
