Wanting to enjoy the beautiful weather, Cassie took a walk with no destination in mind. At each four-way intersection, she randomly decided to head either south or west.  A summary of her walk is shown below.

Is there evidence at the α = 0.05 level of significance to support the hypothesis that Cassie's walk was not random?
◦ z = -0.91
Since |z| < z0.025 = 1.96, we do not reject H0. There is not sufficient evidence to support the  hypothesis that her walk was not random.
◦ z = -5.43
Since |z| > z0.025 = 1.96, we reject H0. There is sufficient evidence to support the hypothesis that her walk was not random.
◦ z = -3.50
Since |z| > z0.025 = 1.96, we reject H0. There is sufficient evidence to support the hypothesis that her walk was not random.
◦ z = -0.26
Since |z| < z0.025 = 1.96, we do not reject H0. There is not sufficient evidence to support the  hypothesis that her walk was not random.
