A rare form of malignant tumor occurs in 11 children in a million, so its probability is 0.000011. Four cases of this tumor occurred in a certain town, which had 19,809 children

d. Let a probability of 0.05 or less be "very small," and let a probability of 0.95 or more be "very large". Does the cluster of four cases appear to be attributable to random chance? Why or why not?

Yes, because the probability of more than one case is very large.

No, because the probability of more than one case is very large.

No, because the probability of more than one case is very small.

Yes, because the probability of more than one case is very small.

Step 1

d.

From the given information, the probability is 0.000011 and the number of children is 19,809. That is, *p*=0.000011 and *n*=19,809.

Let us define the random ...
