Answer

Explanation:

Step1: Identify the proportion

The confidence level is 68%, which means the proportion of samples' confidence - intervals that contain the population mean is 0.68.

Step2: Calculate the number of samples

We have 200 samples. Multiply the total number of samples by the proportion. Let (n) be the number of samples whose confidence - intervals contain the population mean. Then (n = 200\times0.68). [n=200\times0.68 = 136]

Answer:

136
