Answer: The z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.

Step-by-step explanation:

Given: Average monthly electric bill in Illinois = $83

Average monthly electric bill in Florida = $102

Formula of z : z=\dfrac{X-mean}{standard\ deviaton}

In Illinois, the mean monthly electric bill is $85, with a standard deviation of $3.20.

z=\dfrac{83-85}{3.20}= -0.625

In Florida, the mean monthly electric bill is $105, with a standard deviation of $4.00.

z=\dfrac{105-102}{4}=\dfrac{3}{4}=0.75

Hence, the z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.
