Answer:
Tanner's score = 70
Step-by-step explanation:
Data provided in the question:
Mean value of the statistics test taken by Tanner = 80
Standard deviation = 5
Total points possible = 100
Now,
It is given that the Tanner's score was 2 standard deviation below the mean
Mathematically,
Tanner's score = Mean - ( 2 × Standard deviation )

Tanner's score = 80 - ( 2 × 5 )
or
Tanner's score = 80 - 10
or
Tanner's score = 70
