Simple equation and only requires one step to solve. Remember, a number and a variable juxtaposed means multiplications.
One step? I know. It seems more because I was slowing down the calculations for you so could understand everything happening. For someone who can do this in their sleep it would, for them, take one step.
Answer:
C) The mean of this data set is 12.
Step-by-step explanation:
When you add all of the numbers together you get 102.
13+11+16+12+42+8 = 102
Divide this by 66 because that is how many numbers are being used.
102/6 = 17 is the mean

Answer:
i think its 5%
Step-by-step explanation:
because if you divide 40 by 8 you get 5
Answer:
9 inches
Step-by-step explanation:
The population is within 6 standard deviations of the mean with a confidence of 99.7 percent, 3 above and 3 below
The standard deviation of the sample mean is equal to the population standard deviation divided by the square root of the sample size
population standard deviation = 36
sample size = 144
standard deviation of the sample mean = 36/ sqrt(144)
=36/12
=3
The margin of error is the number of standard deviations above the mean * the standard deviations
margin of error = 3 * 3
= 9 inches
