The letter "t" makes up an estimated 8% of a certain language. Assume this is still correct. A random sample of 1000 letters is taken from a randomly selected, large book and the t's are counted. Find the approximate probability that the random sample of 1000 letters will contain 7.4% or fewer t's. P(ps0.074) -(Round to three decimal places as needed.)

**Title: Probability Calculation of Letter Frequency in a Sample**

**Content:**

The letter "t" makes up an estimated 8% of a certain language. Assume this is still correct. A random sample of 1,000 letters is taken from a randomly selected, large book and the t’s are counted.

*Objective:* Find the approximate probability that the random sample of 1,000 letters will contain 7.4% or fewer t’s.

**Notation Used:**
\( P(\hat{p} \leq 0.074) \) = [Input box for answer] (Round to three decimal places as needed.)

**Explanation:**

This problem involves the application of probability concepts to determine the likelihood of a given letter frequency within a sample size. The expected proportion of the letter “t” is given as 8% in general use, and the task is to determine the probability of observing a proportion of 7.4% or fewer in a sample of 1,000 letters.

To accurately determine this probability, one might use statistical methods such as the normal approximation to the binomial distribution, given the large sample size:
- Calculate the standard deviation of the sample proportion.
- Use the normal distribution to approximate the probability, considering the context of the values provided.

The answer should be computed and rounded to three decimal places.
