Answer:

0.0802 = 8.02% probability that the sample mean would differ from the population mean by more than 2.2 millimeters

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Their current steel bolts have a mean diameter of 148 millimeters, and a standard deviation of 7 millimeters.

This means that [tex]\mu = 148, \sigma = 7[/tex]

Sample of 31:

This means that [tex]n = 31, s = \frac{7}{\sqrt{31}}[/tex]

What is the probability that the sample mean would differ from the population mean by more than 2.2 millimeters?

Less than 148 - 2.2 = 145.8 or more than 148+2.2 = 150.2. Due to the simmetry of the normal distribution, these probabilities are the same, which means that we find one and multiply by 2.

Probability of being less than 145.8:

The pvalue of Z when X = 145.8. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{145.8 - 148}{\frac{7}{\sqrt{31}}}[/tex]

[tex]Z = -1.75[/tex]

[tex]Z = -1.75[/tex] has a pvalue of 0.0401

2*0.0401 = 0.0802

0.0802 = 8.02% probability that the sample mean would differ from the population mean by more than 2.2 millimeters

Answer:

y = x

Step-by-step explanation:

Hi,

We know that in the equation...

y = mx + b

m = slope

So, to find the equation of the line, we have to plug in what we already know. So...

-7 = 1 (-7) + b

Solve...

-7 = -7 + b

b = 0

That means that your equation is...

y = x

(you don't have to put the one in front of the x)

I hope this helps :)

Answer:

Probability that [tex]-5 \leq x \leq 5[/tex] is 0.3

Step-by-step explanation:

From the table, we have that the probability is:

[tex]P(-5 \leq x \leq 5) = P(x = -5) + P(x = 0) + P(x = 5)[/tex]

With the values given

[tex]P(-5 \leq x \leq 5) = P(x = -5) + P(x = 0) + P(x = 5) = 0.15 + 0.05 + 0.1 = 0.3[/tex]

So

Probability that [tex]-5 \leq x \leq 5[/tex] is 0.3

Answer:

[tex]Area = 400m^2[/tex]

Step-by-step explanation:

Given

[tex]a = 10m[/tex] --- apothem

Required

The area of the square

The relationship between the apothem (a) and the length (L) of  1 side of a square is:

[tex]a = \frac{L}{2}[/tex]

Make L the subject

[tex]L = 2a[/tex]

Substitute [tex]a = 10m[/tex]

[tex]L = 2*10m[/tex]

[tex]L = 20m[/tex]

The area is then calculated as:

[tex]Area = L^2[/tex]

So:

[tex]Area = (20m)^2[/tex]

[tex]Area = 400m^2[/tex]

Answer:

40 pieces

Step-by-step explanation:

To make it easier, I'm gonna divide 15 by 3 and then multiply it by 2. Same with 6.

10% of candy = 4 pieces.

Multiply by 10

100% of candy = 40 pieces.

Answer:

Yes, you're correct.

An example would be, say, 345. You want to find 60%. So you multiply 345 by 0.60.

Answer:

Multiplying by 5 isolates the x on one side of the equation

Step-by-step explanation:

This is so you can solve for the variable x.  By isolating you get the get the variable on its own so you know what the varible itself is equal to, which in this case is 75.

Answer:

Multiplying by 5 isolates x on one side of the equation

Step-by-step explanation:

When you solve equations like that, your goal is to get the variable by itself

e. A matched pairs t-test for a mean difference

Step-by-step explanation:

When the observations from two samples are paired either naturally or by design we find the differences between the two observations of each pair.Treating the differences as a random sample from a normal population with mean ud= u1-u2 and unknwn standard deviation σd we perform one sample t- test on them. This is called the paired difference t- test or a paired t- test.

Suppose 10 young recruits are given a physical training by the Army . Their weights are recorded before and after the training. These observations constitutes natural pairing .

When we eliminate the undesireable sources of variation to take observations in pairs , this is called pairing by design.

Answer:

a10 = 15

an = 6n - 45

Step-by-step explanation:

a12 = 27 = a + 11d - eq 1

a14 = 39 = a + 13d - eq 2

eq 2 - eq 1

2d = 12

d = 6

a + 11(6) = 27

a + 66 = 27

a = -39

a10 = a + 9d = -39 + 9(6) = 15

Tn = a + (n-1)d

-39 + 6(n - 1)

-39 + 6n -6

an = 6n - 45

Answer: if x is to the 2 power then

kx^2+12x-4=0         Add 4 to the both sides

kx^2+12x=4             Divide both sides by 12

kx^2=1/3x                square root the both sides

k=0.6x

Answer:

v=3.2

Step-by-step explanation:

Let's solve your equation step-by-step.

−12.3+7v=10.1

Step 1: Simplify both sides of the equation.

7v−12.3=10.1

Step 2: Add 12.3 to both sides.

7v−12.3+12.3=10.1+12.3

7v=22.4

Step 3: Divide both sides by 7.

7v /7 = 22.4 /7

v=3.2

Answer:

86

Step-by-step explanation:

Answer:

90

Step-by-step explanation:

1. The other angle marked with one arc must also be 43 deg.

2. The two angles put together make an angle of 86 deg.

3. In a parallelogram, the angle at lower right and the angle at upper right are supplementary (they add up to 180 deg.). The upper right angle is 180 - 86 = 94 deg.

4. The angle at lower left is the same, 94 deg.

5. The angles marked with two arcs are half of 94 deg. = 47 deg.

6. Now you have two out of three angles in the triangle. All three angles add up to 180 deg. so the measure of angle 1 is 180 - 47 - 43 = 90 degrees.
