Answer:
Mean: 13
SD:
Step-by-step explanation:
To find the mean, you have to add up all of them and divide by the number of them. The sum is 30+30+18 or 78, and there are 6 so the mean is 78 / 6 = 13.
To find the standard deviation, we need to first find the distance from them to the mean. These are 2, 3, 3, 3, 5, and 2. Square these values to get 4, 9, 9, 9, 25, and 4. Now we have to take the mean of this, which is 8+27+25=35+25=60, so the mean is 10 and now we take the square root so the SD is .
in short, we will start off by making the left-side of the dot and the recurring numbers a variable, say "x", then multiplying it by some power of 10 that moves the recurring numbers over to the left, let's do so
