Question

at longs donuts the number of donut holes in a bag can vary. what is the mode of the given values? 12,10,10,10,13,12,11,13,10 question 4 1 pts calculate the mean of this group of numbers: 2,9,10,6,8

Explanation:

Step1: Recall mode definition

The mode is the number that appears most frequently in a data - set.

Step2: Count frequencies

For the data - set 12, 10, 10, 10, 13, 12, 11, 13, 10:

• 10 appears 4 times.
• 11 appears 1 time.
• 12 appears 2 times.
• 13 appears 2 times.

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.

Step2: Calculate sum of data points

For the data - set 2, 9, 10, 6, 8, $\sum_{i=1}^{5}x_{i}=2 + 9+10 + 6+8=35$.

Step3: Calculate the number of data points

$n = 5$.

Step4: Calculate the mean

$\bar{x}=\frac{35}{5}=7$.
