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 127 students who participated in the​ study, 98 correctly identified the color of the gummy bear. Complete parts a through c below.

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

​(Type an integer or a decimal. Do not​ round.)

Answer 1

GIVEN THAT :-

According to the above question we have that ,

total number of students = 127=x

the number of students identifying the colour = 98=n

TO FIND:-proportion of the population of students will correctly identify the​ color

so for finding the proportion of the population of students will correctly identify the​ color we have a formula

P=x/n

substituting the values of x,n we get that

Proportion =98/127

=0.77135

so now we have

the proportion of the population of students will correctly identify the​ color is 0.77135.
