For a Chi-Squared Goodness of Fit Test about a distribution that has the following characteristics: Category 1: 50% Category 2: 15% Category 3: 20% Category 4: 15% complete the table. Round to the fourth as needed. Categories | Observed Frequency | Expected Frequency 1 | 345 | 2 | 112 | 3 | 142 | 4 | 150 |

Step 1
First, we need to find the total number of observations. To do this, we add up the observed frequencies for each category: Total observations = 345 + 112 + 142 + 150 = 749 Show more…
