Question

Our experiment begins with a jar containing equal amounts of black and white beans (consider it a 1:1 ratio of black to white beans). From this sample, a petri dish was filled and the number of black and white beans was counted and recorded. For example, one student counted 46 black beans and 42 white beans Based on the assumption that the jar contained an equal ratio of black to white beans, how many black and white beans should the student have expected, based on the hypothesis of equal frequency? Select one a. 45 black beans, 37 white beans Ob. 41 black beans: 41 white beans C. 37 black beans; 37 white beans d 44 black beans 44 white beans e. Not enough information to determine 3:58 PM

Explanation / Answer

Answer : d) 44 black beans 44 white beans

As given In the jar tube, equal amounts white beans and black beans are present in the ratio 1:1.

After taking in petri dish we counted total 88 beans out of which 46 were black beans and 42 were white beans.

As we know that there were equal quantity of both beans in the jar, one would expect equal no of white and black beans in the petri dish based on hypothesis of Equal frequency.

Hence petri dish would be expected to have 44 black beans and 44 white beans
