Answer:
0.09 average effect 
Step-by-step explanation:
Given that the t statistics = 1.54
Sample size (n) = 25
Therefore, variance = t²/n
Variance = 1.54²/25
Variance = 2.372/25
Variance = 0.09

One pie costs 0.10
you are buying 40 pies so...
40 x 0.10 = $4
one cup of coffee costs 0.50
you are buying 20 coffee so...
20 x 0.50 = $10
$4 + $10 = $14
It costs $14 to buy 40 pieces of pie and 20 cups of coffee
        
             
        
        
        
A) 3. This is the base number somebody would win without ever practicing. 
B) y = 2x + 3. The slope of the line of best fit, depending on the points you pick, is roughly 2. Thus the answer for 13 would be 29.
