Let X = hourly median power (in decibels) of received radio signals transmitted between two cities. It is believed that the lognormal distribution provides a reasonable probability model for X. If the parameter values are u = 3.5 and a = 1.2, calculate the probability that received power is more than 200 dB.

Question
**Problem Statement**: Determine the probability of a given scenario involving radio signal power.

**Details**:
- Let \( X \) represent the hourly median power (in decibels) of received radio signals transmitted between two cities.
- The lognormal distribution is considered an appropriate model for \( X \).
- Given parameter values:
  - Mean (\( \mu \)) = 3.5
  - Standard deviation (\( \sigma \)) = 1.2
- Task: Calculate the probability that the received power exceeds 200 dB.

**Resource**:
- A downloadable Excel Worksheet is provided to perform calculations or simulations: [Excel Worksheet-1.xlsx](#).

**Options**:
1. 0.0670
2. 0.9330
3. 0.14986
4. 0.2069
5. Something else

**Note**:
- Solve using statistical methods suited for lognormal distributions.
- Useful for applications in radio communications and signal processing analysis.
