D) let= 0.95.

If no knowledge of even the approximate values of the sample proportion $\hat { P }$ is available, it is recommended to use the conservative estimate of 0.50 for the population proportion p. This ensures that the sample size is large enough to provide a reasonable estimate for p, regardless of whether the true value of p is close to 0, 0.5, or 1.0.
