Assess the normality of the following variables: claim amount, coverage, household income, and deductible (explain whether or not the variables are normally distributed, are distribution symmetrical or skewed). Explain your findings and support with descriptives (numerical and/or graphical) 1. claim amount
X squared = 1260620 ; df= 4414 ; p value= 0
2. coverage
X squared = 1540098 ; df= 4414 ; p value= 0
3. income
X squared = 303688.3 ; df= 4414 ; p value= 0
4. deductible
X squared = 2289520 ; df= 4414 ; p value= 0
5. Is there a statistical relationship between claim amount and income? Explain your findings and support with descriptives (numerical and/or graphical)
X squared = 1119220 ; df= 963072 ; p value= 0
6. Is there a statistical relationship between the type of claim and marital status? Explain your findings and support with
descriptives (numerical and/or graphical)
X squared = 4.179577 ; df= 4 ; p value= 0.3822479

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.

i suppose it should be (y=2x-5)

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
