Did you sleep with a comfort object as a child? Do you still? No need to stuff that teddy bear from your infant years in your cl

oset the next time you have a guest over—the odds are good that he or she has a comfort object, too. A study conducted by Sleepopolis and OnePoll reported that 34% of adults still sleep with a stuffed animal, blanket, or other sentimental object, according to a survey of a random sample of 100 adults. A similar study, based on a random sample of 80 children reports that 75% of children sleep with a comfort object.
Do these data provide convincing evidence that the proportion of adults who sleep with a comfort object is less than the proportion of children who sleep with a comfort object? Justify your answer.

I will mark Brainiest (no links please)
Vera_Pavlovna [14]

Answer:

Step-by-step explanation:

Are the volumes equal?      No, so throw out the first and the last one.

Is the volume of the pyramid greater than the volume of prism?  

                                            No, so throw out the third one

so by inspection it must be the remaining one

or mathematically

    vol pyramid = (1/3)(base)(height)

    vol prism     =  (base)(height)

 

              vol pyramid   /   vol prism      

           (1/3)(base)(height) / (base)(height)   = 1/3
