Hey josephnmorris12, good to see you again. Here is the completed frequency table and the required sums. Step 1: Calculate the Cumulative Frequency (CF). The cumulative frequency for each row is the sum of the frequencies up to that row. Step 2: Calculate f_i X_i. Multiply each frequency (f_i) by its corresponding value (X_i). Step 3: Calculate X_i^2. Square each value (X_i). Step 4: Calculate f_i X_i^2. Multiply each frequency (f_i) by its corresponding squared value (X_i^2). Step 5: Calculate the sums. Sum the values in the f_i, f_i X_i, and f_i X_i^2 columns. The completed table is: |c|c|c|c|c|c| X_i & f_i & CF & f_i X_i & X_i^2 & f_i X_i^2 \\ 1 & 3 & 3 & 3 & 1 & 3 \\ 2 & 12 & 15 & 24 & 4 & 48 \\ 3 & 6 & 21 & 18 & 9 & 54 \\ 4 & 5 & 26 & 20 & 16 & 80 \\ 5 & 0 & 26 & 0 & 25 & 0 \\ 6 & 3 & 29 & 18 & 36 & 108 \\ 7 & 1 & 30 & 7 & 49 & 49 \\ & 30 & & 90 & & 342 \\ The required sums are: f_i = 30 f_i X_i = 90 f_i X_i^2 = 342 Send me the next one 📸
