Question

An entomologist writes an article in a scientific journal which claims that fewer than 14 in ten thousand male fireflies are unable to produce light due to a genetic mutation. Use the parameter p, the true proportion of fireflies unable to produce light. An entomologist writes an article in a scientific journal which claims that fewer than 14 in ten thousand male fireflies are unable to produce light due to a genetic mutation. Use the parameter p, the true proportion of fireflies unable to produce light.

Explanation / Answer

proportion value = x/n

= 14/10000= 0.0014

Null hypothesis is defined as

H0: p>= 0.0014

Alternative hypothesis is defined as

H1: p< 0.0014
