Difficulty: 3 | Problem written by peter.washington
Implement a linear regression model used to predict the monthly premium someone is willing to pay for a health insurance policy. The input values are:

• Credit_Score - a value between 0 and 800
• Gender - male (0) or female (1)
• Age (in years) - a value between 18 and 100
• Income_Group - a value representing the income group of the customer, with values ranging from 1 to 10

Here is the model:

Expected_Health_Premium = exp(0.05 * Gender + 0.003 * Credit_Score + 0.008 * Age + 0.01 * Income_Group + 2.1)

The input to the model will be a JSON string which you must parse.

Sample Input:
<class 'dict'>
json_data: {"Credit_Score": 800, "Gender": "Female", "Age": 20, "Income_Group": 7}

Expected Output:
<class 'float'>
