Answer:
Mean = 78 ;
Standard deviation = 14
Step-by-step explanation:
Given that:
Mean score = 68
Standard deviation = 14
When a constant value is added to the individual value of a dataset, the new mean value will become the sum of the initial mean value and the constant term added to the values.
Constant Added score = 10
The mean of scaled test score will be:
Mean score + constant added score
68 + 10 = 78
The standard deviation remains unchanged ; Hence, standard deviation = 14
