In a study of automobile collision insurance costs, a random sample of n = 35 repair costs of front-end damage caused by hitting

laiz [17]

Answer: The maximum error = $105.76.

Step-by-step explanation:

Formula to find the maximum error:

$E= z^*\dfrac{\sigma}{\sqrt{n}}$

, where n= sample size.

$\sigma$ = Population standard deviation

z*= Critical value(two-tailed).

As per given , we have

$\overline{x}=1438$

n= 35

$\sigma=269$

For 98% confidence , the significance level = $1-0.98=0.02$

By z-table , the critical value (two -tailed) = $z^* = z_{\alpha/2}=z_{0.01}=2.326$

Now , the maximum error = $E= (2.326)\dfrac{269}{\sqrt{35}}$

$E= (2.326)\dfrac{269}{5.9160797831}$

$E= (2.326)\times45.4692989044=105.761589252\pprox105.76$

Hence, With 98% confidence level , the maximum error = $105.76.

lesantik [10]

First do -x then -x to 4x so you have 3x-6=9.
Add 6 to -6 to cancel it out, then add 6 to 9.
3x-6. Divide 3from x, divide 3from 6. X=2. Plz answer my question too plz
