Give a null hypothesis for a goodness-of-fit test and a frequency table from a sample. For each table, find:
(a) The expected count for the category labeled B
(b) The contribution to the sum of the chi-square statistic for the category labeled B
(c) The degrees of freedom for the chi-square distribution for that table.

H₀: p_a = p_b = p_c = p_d = 0.25
H_a: Some p_i ‰ 0.25

Total A B 40 36 49 35 D 160
