Answer:
3.06
Step-by-step explanation:
The correct answer is - 3.06
Reason -
For sample A :
mean, 
= 8.05
Standard deviation, 
= 1.36
Size, 
= 50
For sample B :
mean, 
= 7.26
Standard deviation, 
= 1.06
Size, 
= 38
Now,
- = 8.05 - 7.26 = 0.79
Standard deviation error, SE = √(²/ + ²/) = 0.2580
Now,
Z-statistic = ( - )/ SE
= 0.79/0.2580
= 3.06
⇒Z-statistic = 3.06
