The table is missing in the question. The table is provided here :
Group 1 Group 2
34.86 64.14 mean
21.99 20.46 standard deviation
7 7 n
Solution :
a). The IV or independent variable = Group 1
The DV or the dependent variable = Group 2
b).


Therefore, 

t = -2.579143
Now, 
df = 7 - 1
= 6
Therefore the value of p :

= 0.020908803
The p value is 0.0209

So we reject the null hypothesis and conclude that 
3+6=9
The time would be 9:05
Answer: 35 pies
Step-by-step explanation:
Ken can bake 1 pie with each additional cup of sugar he buys. 1 pie =1 cup
4 + x = y
Where;
x= additional pies
y= total pies
If 1 cup= 1 pie; then 31 cups =
31 cup × 1 pie/1 cup = x
:. x= 31 pies
y= x + 4
y= 31+4 = 35
