Transcribed Image Text:### Understanding Treatment Efficacy: Mild vs. Severe Acne Treatments
To answer the question about the following table, which displays the results of different treatments for mild and severe acne, review the details below:
#### Table: Comparison of Treatment Outcomes for Mild and Severe Acne
| | **Mild Acne** | | | **Severe Acne** | |
|----------------|--------------------|-----------|------------|--------------------|------------|
| | **Cured** | **Not Cured** | **Cured** | **Not Cured** |
| **Old Treatment** | 1 | 4 | 43 | 43 |
| **New Treatment** | 26 | 52 | 14 | 10 |
#### Explanation of the Table
- **Old Treatment for Mild Acne:**
- **Cured:** 1 person
- **Not Cured:** 4 people
- **New Treatment for Mild Acne:**
- **Cured:** 26 people
- **Not Cured:** 52 people
- **Old Treatment for Severe Acne:**
- **Cured:** 43 people
- **Not Cured:** 43 people
- **New Treatment for Severe Acne:**
- **Cured:** 14 people
- **Not Cured:** 10 people
#### Question:
What does the number "10" in the lower right cell of the table mean?
- **Answer Choices:**
- **A.** 10 people with severe acne were cured by the new treatment.
- **B.** 10% of people with severe acne were not cured by the new treatment.
- **C.** 10% of people treated with the new treatment had severe acne and were not cured.
To find the correct answer, examine the placement of the number "10" (New Treatment, Severe Acne, Not Cured).
#### Correct Answer:
- **B.** 10% of people with severe acne were not cured by the new treatment.
**Explanation:**
The number "10" represents the individuals with severe acne who were not cured using the new treatment. This does not indicate a percentage but a raw count of the individuals who were not cured. Therefore, the correct interpretation directly from the table data should reference the number of people, not a percentage.

Historical records show that 80% of test subjects pass the test. To pass the test, a subject must exactly repeat all the digits in the number after two hours. A random sample of 625 people to take the memory test is going to be chosen. Let p be the proportion of people in the sample who pass the test. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of P. 0 (b) Find the standard deviation of p. 0 (c) Compute an approximation for P(P >0.84), which is the probability that more than 84% of the people in the sample pass the test.
