4. The angle that a spider's web makes with a line vertical to the earth's surface varies by species. For example, for Isoxya cicatricosa this angle has been shown to have a mean of 28.12°. The angles for 5 webs of an unknown species are shown below: 25° 12° 31° 26° 17° ban gal Using a significance threshold of a = 0.02, and assuming that web angles are normally distributed, is there enough evidence to show that these webs were not made by Isorya cicatricosa?
