Question

A magazine presented a lesson in hypothesis testing carried out by medical students in a biostatistics class. Students were​ blind-folded and then given a​ red-colored or​ yellow-colored gummy bear to chew.​ (Half the students were randomly assigned to receive the red gummy bear and half to receive the yellow bear. The students could not see what color gummy bear they were​ given.) After​ chewing, the students were asked to guess the color of the candy based on the flavor. Of the 123 students who participated in the​ study, 70 correctly identified the color of the gummy bear.

If there is no relationship between color and gummy bear flavor, what proportion of the population of students will correctly identify the color?

Answer 1

p = 0.5

Explanation:

in order to determine what proportion of the population of students will correctly identify the color

given that

n = 123

x = 70

sample proportion P = X/N = 70/123

P = 0.569
