a).in the sample of thyroid cancer the proportion of children with an estimated thyroid dose in the <0.30 gy interval is:- (61/123)
in the sample of without thyroid cancer the proportion of children with an estimated thyroid dose in the <0.30 gy interval is:- (78/123)
b).null hypothesis:the proportion across the three dose intervals are same for both the population.
alternative hypothesis:the proportion across the three dose intervals are different across the two population.
c).the expected cell count of children with an estimated thyroid dose in the <0.30 gy in the sample with thyroid cancer is:- 69.50
d).the contribution of the first row and first column is:- 1.040
e).the value of test statistic:- 5.169 ~ 5.2
f).because the value of degree of freedom for the chi-square test is:- 2
g).accept the null hypothesis.
you can not conclude that the proportion across the three dose intervals are different.
