Answer:
B. This statement is false. A true statement is, "As the size of a sample increases, the standard deviation of the distribution of sample means decreases
Step-by-step explanation:
Standard deviation of distribution of sample means =
Sample size = n
Population standard deviation =
The formula to calculate the standard deviation of distribution of sample means is:
From the above relation we can see that:
Standard deviation of the distribution of sample means is inversely related to the sample size. In inverse relation if one quantity increases the other will decrease. So, if the size of the sample is increased, the standard deviation of the distribution of sample means will Decrease.
Hence, the given statement is False. Therefore, the correct answer will be:
B. This statement is false. A true statement is, "As the size of a sample increases, the standard deviation of the distribution of sample means decreases"

Answer:
First, our answer is 18 yards long.
Step-by-step explanation:
It is 18 yards long because first, we have 9, the length of Jamie's car. Joey's car length is 27 feet. Then, since 1 foot converted is 0.333333...., it is very hard to convert so i turn it in to 9 foot converted into 3 yards. Then, both sides multiply by 3 so 27 foot equals to 9 yards. 9 yards+9 yards equals 18 yards.
Hope it helps Hailey!

Answer:
15$
Step-by-step explanation:
Step 1: First determine the value of the whole amount, which is 50.
Step 2: Determine the percentage, which is 30.
Step 3: Convert the percentage 30% to its decimal form by dividing 30 into 100 to get the decimal number 0.3:
30/100 = 0.3
(Dividing into 100 is the same as moving the decimal point two places to the left.)
30.0 → 3.00 → 0.30
Step 4: Finally, find the portion by multiplying the decimal form, found in the previous step, by the whole amount:
0.3 x 50 = 15 (answer).
Hope this helps.
