Given the following choices, select the best hypothesis test to use in this situation.12 participants are randomly selected by their GP to assess the effects of eating fruit on blood sugar levels (mmol/L). Their blood sugar levels were measured for each participant upon entering the trial and again one hour later after eating three pieces of fruit.

Students are setting up an experiment to determine what food source is most beneficial for fruit flies. Students create a choice chamber, shown below, that has two main chambers in it. One chamber is empty, and the other chamber has pieces of banana in it.Created for Albert. All rights reserved.After conducting the experiment, students learned that different food groups may have a different effect on fruit flies.Given the new information, what should the next steps be in this study?Elimination ToolSelect one answerACompare two different types of bananas in the choice chamber.BCompare protein with fats in the choice chamber.CCompare the banana to a protein food source in the choice chamber.DCompare sugar water to regular water in the choice chamber.S

Decide which hypothesis test is appropriate to use.A BBQ restaurant chain wanted to compare ratings for their BBQ orders for different flavored wood chips they use in their BBQ. They use the same meat to barbecue for 4 different flavored wood chips: mesquite, cherry wood, hickory, and apple wood. They compared consumer ratings for each (poor, OK, good, excellent).Group of answer choicesHypothesis testing for one population proportionHypothesis testing for one population meanHypothesis testing comparing two population proportionsHypothesis testing comparing two population means – independent samplesHypothesis testing comparing two population means – matched pair samplesANOVAChi-square test of independenceT-test for linear relationship

Each participant ate one type of fruit.Organic Non-organicApples 5 6Peaches 2 5What is the probability that a randomly selected participant tasted peaches or preferred organic?Simplify any fractions.

To ascertain the effectiveness of a new, quicker, and simpler test for identifying diabetes, a study was undertaken involving 739 participants. With this test, a positive result indicates the presence of diabetes. A negative result indicates the absence of diabetes. Data collected to assess the effectiveness of this new test revealed: 201 of the participants confirmed they actually had diabetes, with the other participants confirming they actually did not have diabetes. 124 participants actually had diabetes and produced a negative test result. 255 participants produced a negative test result. A participant from the study is chosen at random. What is the probability they do actually have diabetes given the test result is positive? (3 decimal places)
