Question 1

Formulate the null and alternative hypotheses for a hypothesis test.

A manufacturer wishes to test the claim that one of its pancake mixes has a mean weight that does not equal 16 ounces as advertised.
◦ H0:  μ = 16 ounces
Ha:  μ > 16 ounces
◦ H0:  μ = 16 ounces
Ha:  μ ≠ 16 ounces
◦ H0:  μ ≠ 16 ounces
Ha:  μ = 16 ounces
◦ H0:  μ = 16 ounces
Ha:  μ < 16 ounces

Question 2

Solve the problem.

An entomologist writes an article in a scientific journal which claims that fewer than 20 in ten thousand male fireflies are unable to produce light due to a genetic mutation. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms.
◦ There is not sufficient sample evidence to support the claim that the proportion is less than 20 in ten thousand.
◦ There is not sufficient sample evidence to support the claim that the proportion is greater than 20 in ten thousand.
◦ There is sufficient sample evidence to support the claim that the proportion is less than 20 in ten thousand.
