Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol (µ, p, Η)for the indicated parameter. 1) 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. 1) A) H0: p < 0.0007 H1: p L 0.0007 B) H0: p > 0.0007 H1: p K 0.0007 C) H0: p = 0.0007 H1: p > 0.0007 D) H0: p = 0.0007 H1: p < 0.0007

out of those given id have to say D
null hypothesis is no corrolation of claims made. he claims less than 7/10k, so null is where p = 7/10k
alternatte hypothesis is contrary to null.

null hypo = h subscript 0: p = 0.0007
alternate hypo: h subscript 1: p < 0.0007
