25. A numerical taxonomist studying the branched filamentous alga, Cladophora glom- erata, believes she has discovered a new species. C. glomerata has a median branch- ing angle of 470. While the new species is quite similar to C. glomerata, she believes the branching angle is less than that of C. glomerata. Measuring 17 specimens she collected, she found the branching angles below. Are the angles of her sample specimens significantly smaller than those of C. glomerata? 420 40 390 450 490 450 430 380 390 420 410 40 350 410 40 40 470
