Answer:Option C) 0.830

Step-by-step explanation:We are

given the followingin the question:The heights (in inches) of males in the United States are believed to be approximately normally distributed with mean .

Sample size, n = 25

Sample mean, = 69.72 inches

Standard deviation, = 4.15 inches

We have to find the standard error of .

Standard error =Thus, the standard error ofis 0.83 inches.The correct answer is

Option C)0.830
