Ha : The proportion of male fireflies that cannot produce light due to mutation is not equal to 15c . implement two- tailed Z-testd . Z- tabular 1 .645e . Use Code 8 .4f . Test statistic -1 .353g . Since -1 .353 is less than Z- tabular , then we have sufficient evidence to conclude that the proportion of male fireflies that cannot produce light due to a genetic mutation is equal to 1511 . a .
