For numbers 1 to 4: The vitamin content of the flesh of each of a random sample of eight oranges and of a random sample of five lemons was measured. The results are given in milligrams per 10 grams. Citrucy, a biology student, claims that there is no significant difference between the two. 3. The appropriate alternative hypothesis to verify Citrucy's claim is A. u_orangeμ_lemon O C. u_orange*μ_lemon O D. μ_orangezμ_lemon

Citrucy, a biology student, claims that there is no significant difference between the two. 4. If the test yielded a p-value = 0.08, we Ho. Hence, at 10% level of significance, we have evidence to say that the mean vitamin content (in milligrams per 10 grams) of oranges is different from the mean vitamin content (in milligrams per 10 grams) of lemons.

Follow-up Question

 

Which of the following is(are) TRUE?
