the following table shows the number of lemons that grew on marys lemon tree each season last year. season number of lemons winter 3 spring 15 summer 21 fall 13 find the mean number of lemons.
Answer
Explanation:
Step1: Recall mean formula
The mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $x_{i}$ are the data - points and $n$ is the number of data - points. Here, $n = 4$, $x_1=3$, $x_2 = 15$, $x_3=21$, $x_4 = 13$.
Step2: Calculate the sum of data - points
$\sum_{i=1}^{4}x_{i}=3 + 15+21+13=52$.
Step3: Calculate the mean
$\bar{x}=\frac{52}{4}=13$.
Answer:
13
