Exercise 14.1

Answer: The mean number of plants per house is 8.1. The direct method was used because the numerical values of f_i and x_i are small, making calculations easy.

Exercise 14.2

Exercise 14.3

Exercise 14.4

- Create a frequency distribution table with class intervals, frequencies (f_i), class marks (x_i), and the product f_i * x_i.
- Calculate the class mark (x_i) for each interval as (Upper class limit + Lower class limit) / 2.
- Calculate the product f_i * x_i for each row.
- Sum all frequencies (Σf_i) and all products (Σf_i * x_i).
- Apply the formula for the mean (x̄) = Σf_i * x_i / Σf_i.
- State the method used and the reason for choosing it.
