The marketing manager for an automobile manufacturer is interested in determining the proportion of new compact-car owners who would have purchased a passenger-side inflatable airbag if it had been available for an additional cost of $300. the manager believes from previous information that the proportion is 0.30. suppose that a survey of 200 new compact-car owners isselected and 79 indicate that they would have purchased the inflatable air bags. if you were to conduct a test to determine whether there is evidence that the proportion is different from 0.30 and decided not to reject the null hypothesis, what conclusion could you draw?
a)there is not sufficient evidence that the proportion is not 0.30.
b)there is sufficient evidence that the proportion is 0.30.
c)there is sufficient evidence that the proportion is 0.30.
d)there is not sufficient evidence that the proportion is 0.30.

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'

if it is for a job, then you should learn everything you can about the job, like what does it involve, what qualification is required and how you are the right person for that job. dress appropriately for the interview. get plenty of rest the night before. good luck!
