Answer:
Invalid statement: There is exactly 1 yellow marble in the box
Step-by-step explanation:
The probability of finding a yellow marble is Py = 1/30, according to the sample. Then, the number of yellow marbles expected to find in the box is:
N x Py > 1 ,
where N = 250 (number of marbles in the box).
Thus, we expect to find more than one yellow marble in the box and the Invalid statement is: "There is exactly 1 yellow marble in the box".
