In studies for a medication, 7 percent of patients gained weight as a side effect. Suppose 652 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 46 patients will gain weight as a side effect. (b) no more than 46 patients will gain weight as a side effect. (c) at least 59 patients will gain weight as a side effect. What does this result suggest? (a) P(46)= (Round to four decimal places as needed)

Transcribed Image Text:**Probability Analysis of Medication Side Effects**
In studies for a medication, 7 percent of patients gained weight as a side effect. Suppose 652 patients are randomly selected. Using the normal approximation to the binomial, we want to approximate the probability that:
1. **Exactly 46 patients will gain weight as a side effect.**
2. **No more than 46 patients will gain weight as a side effect.**
3. **At least 59 patients will gain weight as a side effect.**
Let's solve the specific cases provided:
### (a) Exactly 46 Patients
**Problem:**
(a) P(46) = ___ (Round to four decimal places as needed)
### Instructions:
1. Utilize the normal approximation method to approximate the probability.
2. Input the computed value in the box provided.
3. Ensure the final value is rounded to four decimal places.
