Give an example of a polygon that exhibits line symmetry.

\( 2 \sqrt { 3 + 2 \sqrt { 3 + 2 \sqrt { 3 + 2 \sqrt { 3 + 2 \sqrt { 3 + \ldots } } } } } \)

Consider the hypotheses: \( H_{0}: \mu=75 \) against \( H_{1}: \mu<75 \). Assume that a random sample of 100 observations yielded a sample mean of 70 and that the population standard deviation is 30 . The \( p \)-value of the test is
