Point J will be moved to points (-5,-7). Point K will be moved to (-8,-7). Point L will be moved to (-9,3).
Look on a greater and less then calc
Draw a circle.
Split the circle into 5 sections. This represents the 5 inches.
Fill in 2 of those sections, those represent the reduction in height.
Count the empty sections. 5 -2 = 3 sections
Now you find the percent. 3/5 = 60%
I believe the answer is the first option.
Answer:
The sampling distribution of the sample average score for this random sample of 64 students is approximately normal, with mean 19.6 and standard deviation 0.625.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 19.6 and a standard deviation of 5.0.
This means that ![\mu = 19.6, \sigma = 5](https://tex.z-dn.net/?f=%5Cmu%20%3D%2019.6%2C%20%5Csigma%20%3D%205)
What is the sampling distribution of the sample average score for this random sample of 64 students?
By the Central Limit Thoerem, the sampling distribution of the sample average score for this random sample of 64 students is approximately normal, with mean 19.6 and standard deviation ![s = \frac{5}{\sqrt{64}} = \frac{5}{8} = 0.625](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B5%7D%7B%5Csqrt%7B64%7D%7D%20%3D%20%5Cfrac%7B5%7D%7B8%7D%20%3D%200.625)
