Assuming that this tumor occurs as usual, find the mean number of cases in groups of 18 comma 745 children. b. using the unrounded mean from part (a), find the probability that the number of tumor cases in a group of 18 comma 745 children is 0 or 1. c. what is the probability of more than one case? d. does the cluster of four cases appear to be attributable to random chance? why or why not?

180

step-by-step explanation:

c: lkllmn.

hope it's you

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
