Grade Proportion A 0.25 0.30 C 0.35 D 0.10 The actual distribution for a class of 20 is in the table below. Grade Frequency A 7 B 7 C 5 D 1 State the null and alternative hypotheses. O Ho: The observed class grades fit the expected grades. He: The observed class grades do not fit the expected grades. O H : The distribution of frequency for each grade is not the same. H: The distribution of frequency for each grade is the same. O Ho: The observed class grades do not fit the expected grades. H_: The observed class grades fit the expected grades. O H: The distribution of frequency for each grade is the same. H: The distribution of frequency for each grade is not the same.A teacher predicts what the distribution of grades on the final exam will be and they are recorded in the table below. Grade Proportion A 0.25 B 0.30 C 0.35 D 0.10 The actual distribution for a class of 60 is in the table below. Grade Frequency A 21 B 21 C 15 D 3 What is the ytest statistic? (Round your answer to two decimal places.)The cumulative number of AIDS cases reported for a county is broken down by ethnicity as in the table below. Ethnicity Number of Cases White 2,229 Hispanic 1,157 Black/African-American 457 Asian, Pacific Islander 232 Total = 4,075 The percentage of each ethnic group in the county is as in the following table. Ethnicity Percentage of total county Number expected (round to two population decimal places) White 42.9% 1748.18 Hispanic 26.7% Black/African-American 2.6% Asian, Pacific Islander 27.8% Total = 100% Perform a goodness-of-fit test to determine whether the occurrence of AIDS cases follows the ethnicities of the general population of the county. State H-. O H: The observed observed number of AIDS cases fit the expected number of AIDS cases for the ethnicities of the general population of the county. O H: The distribution of AIDS cases does not follow the ethnicities of the general population of the county. O H_: The distribution of AIDS cases does follow the ethnicities of the general population of the county. O H: The observed number of AIDS cases do not fit the expected number of AIDS cases for the ethnicities of the general population of the county
