Step 1
From the given data, we have: Σ(FX) = 458922 ΣF = 188 Now, we can calculate the mean: µ = 458922 / 188 = 2441.5 Show more…

Use the given frequency distribution to find the class width, class midpoints, and class boundaries. Temperature (°F) Frequency 32-36 1 37-41 3 42-46 5 47-51 11 52-56 7 57-61 7 62-66 1 (a) What is the class width? (Type an integer or decimal) (b) What are the class midpoints? Complete the table below: (Type integers or decimals) Temperature Frequency Midpoint 32-36 1 37-41 3 42-46 5 47-51 11 52-56 7 57-61 7 62-66 1 (c) What are the class boundaries? Complete the table below: (Type integers or decimals) Temperature Frequency Class boundaries 32-36 1 37-41 3 42-46 5 47-51 11 52-56 7 57-61 7 62-66 1
