Answer:
The mean of of the sample mean of these quality checks is 10 and the standard deviation is 0.7155.
Step-by-step explanation:
To solve this question, we use the central limit theorem.
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
In this problem, we have that:
The mean of of the sample mean of these quality checks is 10 and the standard deviation is 0.7155.
I would say it is either median or mode. Both are basically unaffected by outliers. For median, order them smallest to largest. 3,3,4,4,4,5,5,5,5,30. The median is the middle number, or 4.5 because there is an even amount of numbers, and 4.5 is between 4 and 5. The mode is 5 because it occurs the most. I would use the median, but it is completely up to you.
General rule: The angles on a straight line total 180°
The right angle equates to 90°
Since that angle is half of our desired angle, it must mean that 2x + x = 90°
breaking this down, we get 3x = 90° which can be divided to make x = 30°
