A recent report claimed that 13% of students typically walk to school.8 DeAnna thinks that the proportion is higher than 0.13 at
her large elementary school. She surveys a random sample of 100 students and finds that 17 typically walk to school. DeAnna would like to carry out a test at the α = 0.05 significance level of H0: p = 0.13 versus Ha: p > 0.13, where p = the proportion of all students at her elementary school who typically walk to school.

Step-by-step explanation:
Line of symmetry of a figure is an imaginary line about which the figure can be divided into two equal halves.
In other words, a line passing the center of the figure about which we can fold the figure into two halves overlapping each other.
For the trapezoid given in the figure, line of symmetry will be a vertical line perpendicular to the parallel sides.
Therefore, The figure has 1 line of symmetry.
