Question

Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol for the indicated parameter. An entomologist writes an article in a scientific journal which claims that fewer than 7 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.

A) H0: p > 0.0007 H1: p ? 0.0007

B) H0: p = 0.0007 H1: p > 0.0007

C) H0: p < 0.0007 H1: p ? 0.0007

D) H0: p = 0.0007 H1: p < 0.0007

Answer 1

Here claim is that fewer than 7 in ten thousand male fireflies are unable to produce light due to a genetic mutation.

So alternative hypothesis is $H_1:p<0.0007$

So answer is

D) H0 : p 0.00 07H1 : p 〈 0.0007
