Answer:
0.024
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes 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.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
Suppose the true proportion of high school juniors who skateboard is 0.18.
This means that
Samples of 250 high school juniors are taken
This means that
By how much would their sample proportions typically vary from the true proportion?
This is the standard error, so:
So 0.024 is the answer.
W = g.m, with g = 9.8 m/s². If m is in kg, the weight W will be in Newton
a) W= 9.8 x 22.1 = 216.58 Newton
b) W= 9.8 x 33.5 = 328.30 N

Answer: 7.5 items
Step-by-step explanation:
Both Karen and James had 30 stocking items.
Karen bought 35% of her items;
= 35% * 30
= 10.5 items
James has bought 60%;
= 60% * 30
= 18 items
= 18 - 10.5
= 7.5 items
Answer:
what does that mean
Step-by-step explanation:
Answer:
15.68$
Step-by-step explanation:
You calculate the price of one lollipop:
4.48/2= 2.24
The multiply that by 7.
2.24*7= 15.68$
