20%
Step-by-step explanation:
40 pieces total
32 pieces eaten
40 - 32 = 8

Percentage = (8 / 40) x 100% = 0.2 x 100%
Percentage = 20%
Answer:
The margin of error is 3.465
Step-by-step explanation:
Margin of error = t × sd/√n
n = 92, degree of freedom = n - 1 = 92 - 1 = 91, t-value corresponding to 91 degrees of freedom and 90% confidence level is 1.6618, sd = 20
Margin of error = 1.6618×20/√92 = 33.236/9.592 = 3.465
