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 169 students who participated in
the study, 95 correctly identified the color of the gummy bear.
Complete parts a through c below.

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 169 students who participated in the study, 95 correctly identified the color of the gummy bear. Complete parts a through c below. CO. 5 (Type an integer or a decimal. Do not round.) b. Specify the null and alternative hypotheses for testing whether color and flavor are related. Let p be the true proportion of students who are able to correctly identify the color of the gummy bear. Ho: p = 5 Hap (Type integers or decimals. Do not round.) c. Carry out the test and give the appropriate conclusion at a =0.01. Use the p-value of the test to make your decision Identify the test statistic for this test. (Round to two decimal places as needed.) Identify the p-value for this test. (Round to three decimal places as needed.) Make a conclusion. Choose the correct answer below. O A. Do not reject the null hypothesis. There is sufficient evidence to conclude that color and flavor are related O B. Do not reject the null hypothesis. There is not sufficient evidence to conclude that color and flavor are related O C. Reject the null hypothesis. There is sufficient evidence to conclude that color and flavor are related OD. Reject the null hypothesis. There is not sufficient evidence to conclude that color and flavor are related
