Answer:
For this case if we want to conclude that the sample does not come from a normally distributed population we need to satisfy the condition that the sample size would be large enough in order to use the central limit theoream and approximate the sample mean with the following distribution:

For this case the condition required in order to consider a sample size large is that n>30, then the best solution would be:
n>= 30

Find the two perfectly squared factors the multiple to your number.
Take the square root of those perfect factors then multiple them.
The answer is D. When flipping a coin, the probability of getting tails does not change no matter how many times you flip the coin. It will always be 1/2.
The answer is 25.
Explanation: absolute value is always the opposite of the number inside the bars unless if the number is already positive, absolute value is always positive.
