The observed frequencies resulting from the experiment are (Use Table 3): Category Frequency 77 46 79 70 a. Choose the appropriate alternative hypothesis O All population proportions differ from 0.25 O Not all population proportions are equal to 0.25 b. Calculate the critical value at the 10% significance level (Round your answer to 3 decimal places.) Critical value c. Calculate the value of the test statistic.
