The chocolatier hiredprofessional taste testers to participate in an experiment. The chocolatier flipped a coin for each participant. If thecoin landed on heads, the participant tasted the new dark chocolate candy first, then tasted the current darkchocolate candy. If the coin landed on tails, the participant tasted the current dark chocolate candy first, then tastedthe new dark chocolate candy. The participants rated the bitterness of each dark chocolate candy on a scale of to, with being the least bitter and being the most bitter. Using a paired -test to test the belief, the chocolatiercalculated a p-value of .0.274Assuming the conditions for inference have been met, which of the following is the best conclusion for thechocolatier’s hypothesis test?(A)Because the -value is less than any…A medical researcher says that less than 74%of adults in a certain country think that healthy children should be required to be vaccinated.
