Question
Chapter 25, Problem 25.19CYS
To determine
To find: The number of “accidental” injuries from the sample
Expert Solution & Answer
Answer to Problem 25.19CYS
The correct option is (a): 1,552.
Explanation of Solution
Given info:
The survey results were categorized into two categories such “accidental” and “not accidental” are tabulated below:
| Accidental | Not accidental | |
| 8-13 | 205 | 102 |
| 14-18 | 655 | 916 |
| 19-22 | 239 | 533 |
| 23-30 | 363 | 1,008 |
Reason for correct answer:
The survey results were categorized into two categories such “accidental” and “not accidental” are tabulated below:
| Accidental | Not accidental | |
| 8-13 | 205 | 102 |
| 14-18 | 655 | 916 |
| 19-22 | 239 | 533 |
| 23-30 | 363 | 1,008 |
| Total | 404 | 3,906 |
The total number of accidental injuries in the sample is as follows,
Thus, the correct option is (a) 1,552.
Reason for incorrect answers:
By calculation, the total number of accidental injuries in the sample is 1,552. Hence the options (b) 2,559 and (c) 4,111 are incorrect.
Conclusion:
Thus, total number of accidental injuries in the sample is 1,552.

Suppose the Internal Revenue Service reported that the mean tax refund for the year 2022 was $3401. Assume the standard deviation is $82.5 and that the amounts refunded follow a normal probability distribution. Solve the following three parts? (For the answer to question 14, 15, and 16, start with making a bell curve. Identify on the bell curve where is mean, X, and area(s) to be determined.
1.What percent of the refunds are more than $3,500?
2. What percent of the refunds are more than $3500 but less than $3579?
3. What percent of the refunds are more than $3325 but less than $3579?
