Answer:
5
Step-by-step explanation:
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.
In this problem, we have that:

On average, how much error would be expected between the sample mean and the population mean?
This is the standard deviation of the sample. We have that
. So

The answer is 5.
Answer:
208 km
16 tablets per day
Step-by-step explanation:
Given:
Length of training track run by Jason = 400 m
Number of times Jason ran on the track = 520
Therefore,
The total length covered by Jason = 520 × 400 = 208,000 m
now,
1 Km = 1000 m
thus,
208,000 m =
or
= 208 km
b) Amount of calcium carbonate in a tablet = 500 mg = 0.5 g
Maximum amount of calcium carbonate that can be taken = 8 g
hence,
the maximum number of tablets that she can take
=
=
= 16 tablets per day
Answer:
Yes, they make sense outside the context of temperature.
Step-by-step explanation:
If you are standing in a line, and mark your current position as 0 then if you take two steps ahead it can be counted as positive and if you take two steps back from your current position it can be counted as negative. The positive and negative can denote your forward and backward movement respectively.
If we denote the growth in companies revenue as positive and dip as negative then it would also make sense. A positive number would mean profit for the company while a negative sign would show loss.
The answer would be 1.6 because 2 - 4/5 is 1.2, and then 1.2 x 1/2 is 1.6
Answer:
-
Step-by-step explanation:
This is not solvable, because there is only one equation without an inequality or equal sign.
