Another one Igimoh — let's solve it. The image explains the concept of the Arithmetic Mean or Simple Mean. Step 1: Understand the definition of the Arithmetic Mean. The arithmetic mean, denoted as x (read as "x bar"), is a measure of central tendency. It is calculated by summing all the values in a dataset and then dividing by the total number of values in that dataset. Step 2: State the formula for the Sample Mean. The formula for the sample mean is given by: x = _i=1^n x_in where: • _i=1^n x_i represents the sum of all individual data values. • n represents the total number of data values in the sample. Step 3: Apply the formula to the given example. The example provides a sample of birth weights (in grams) and states that there are n=20 values. Although not all 20 values are fully visible in the image, the sum of these values is given as x_i = 63338 grams. Substitute these values into the formula: x = (63338)/(20) Step 4: Calculate the sample mean. x = 3166.9 The sample mean of the birth weights is 3166.9 g. What's next?
