In a blood donation camp, out of 168 donors, 57 are of blood type O; 77 are blood type A; 25 are blood type B; and 9 are blood type AB. The expected distribution in the entire population is 43% for type O, 41% for type A, 11% for type B, and 5% for type AB. Is there any significant difference between the types of blood donors in the sample and those in the entire camp? Use a 5% level of significance.
