The mean of the samples is 28.25.
The median of the samples is 28.5
The mode of the samples is 35
The standard deviation of the samples is 5.47.
<h3>
Mean of the data points</h3>
The mean for highway mileage (mpg) for a sample of 8 different models of a car company is calculated as follows;
mean = (19 + 22, 26, 27, 30, 32, 35, 35)/8
mean = 28.25
<h3>Median of the data points</h3>
The median is calculated as;
median = (27 + 30)/2 = 28.5
<h3>Mode of the data points</h3>
mode = 35 (it has the highest frequency)
<h3>Standard deviation</h3>
∑(x - x')² = (19 - 28.25)² + (22 - 28.25)² + (26 - 28.25)² + (27 - 28.25)² + (30 - 28.25)² + (32 - 28.25)² + (35 - 28.25)² + (35 - 28.25)²
∑(x - x')² = 239.5
S.D = √[(∑(x - x')² / N]
S.D = √(239.5/8)
S.D = 5.47
