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

Step-by-step explanation:
Answer:
1.5m+1.25j
Step-by-step explanation:
m equals the number of muffins sold, and because each muffin sells for $1.50, 1.5m represents the income made from the muffins.
Same thing with the juice boxes, j equals the number of juice boxes sold, and because each juice box sells for $1.25, 1.25j represents the income made from the juice boxes.
Add the income from both of them to get the total income, and you get 1.5m+1.25j.
