Answer:
The standard deviation for the sample mean distribution is 
Step-by-step explanation:
The central limit theorem states that if you have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population then the distribution of the sample means will be approximately normally distributed.
For the random samples we take from the population, we can compute the standard deviation of the sample means:
From the information given
The standard deviation σ = 136 dollars
The sample n = 45
Thus,
The standard deviation for the sample mean distribution is
28 = k - 12
28 + 12 = k
40 = k
Answer:
a trend line
Step-by-step explanation:
Answer:
The number of tiles are covered by the painting are 12.
Step-by-step explanation:
Consider the provided information.
The painting is covering up some of the tiles on the wall as shown below:
Here it is given that there are 28 squares tiles on the wall.
Total tiles = Number of tiles covered by the painting - uncovered tiles
28 = Number of tiles covered by the painting - 16
Number of tiles covered by the painting = 28 - 16
Number of tiles covered by the painting = 12
Hence, the number of tiles are covered by the painting are 12.
In this picture dots are clearly shown the frequency of the concert.
<h3>What is Frequency?</h3><h3>Frequency refers to the number of times an event or a value occurs. A frequency table is a table that lists items and shows the number of times the items occur.</h3>
Here, in given data about the six concerts
Concerts Frequency
0 2
1 2
2 1
3 1
Thus, on number line we mark 2 dots on zero, 2 dots on one, 1 dot on two and 1 dot on 3.
