Salaries for teachers in a particular elementary school district are normally distributed with a mean of $41,000 and a standard deviation of $7,200. We randomly survey ten teachers from that district. (Round your answers to the nearest dollar.)
(a) Find the 90th percentile for an individual teacher's salary.
$


(b) Find the 90th percentile for the average teacher's salary.
$

Answers

Using the normal distribution and the central limit theorem, it is found that:

a) The 90th percentile for an individual teacher's salary is $50,216.

b) The 90th percentile for the average teacher's salary is $43,914.

In a normal distribution 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]

It 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, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation given by [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this problem:

Mean of $41,000, thus [tex]\mu = 41000[/tex].Standard deviation of $7,200, thus [tex]\sigma = 7200[/tex].

Item a:

The 90th percentile is X when Z has a p-value of 0.9, so X when Z = 1.28. Thus:

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

[tex]1.28 = \frac{X - 41000}{7200}[/tex]

[tex]X - 41000 = 1.28(7200)[/tex]

[tex]X = 50216[/tex]

The 90th percentile for an individual teacher's salary is $50,216.

Item b:

Average for a sample of 10, thus [tex]n = 10, s = \frac{7200}{\sqrt{10}}[/tex].

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

By the Central Limit Theorem

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

[tex]1.28 = \frac{X - 41000}{\frac{7200}{\sqrt{10}}}[/tex]

[tex]X - 41000 = 1.28\frac{7200}{\sqrt{10}}[/tex]

[tex]X = 43914[/tex]

The 90th percentile for the average teacher's salary is $43,914.

There are 28 students in a class. Sixteen of the students are men. What percent of the class are women? Round to the nearest tenth.

42.9%

Step-by-step explanation:

If 16 are men, this means 12 of the students are women (28 - 16 = 12)

So, 12 out of 28 are women = 12 ÷ 28 = 0.42857... = 42.857...% = 42.9%

Find the 16th term of the arithmetic sequence whose common difference is d=9 and whose first term is a, = 1.

Answers

Answer:

136

Step-by-step explanation:

Common difference of 9 means that each term is 9 apart from each other:

1 + 9 = 10 + 9 = 19 + 9 = 28 ...

We can then find the nth term

The difference is 9 → 9n

The 0th term is 1 - 9 = -8

nth term = 9n - 8

Finally plug in (substitute) 16 for n

9(16) - 8 = 144 - 8 = 136

The 16th term is 136

Question : -

Find the 16th term of the arithmetic sequence whose common difference is d=9 and whose first term is a, = 1.

Given : -

common difference ( d ) = 9

first term ( a ) = 1

To Find : -

We have to find the 16th term of Arithmetic Progression or sequence .

Concept : -

Concept of this question belongs to arithmetic progression ( sequence ) where we can find the values of a , d , nth term by using nth term formula .

So Starting the Solution : -

We know that 16th term of a.p. is ,

a + ( 16 - 1 ) d

a + 15 d --------- ( 1 )

Here value of ,

a = 1

d = 9

Substituting, value of a and d in equation 1 :

1 + 15 ( 9 )

1 + 135

136

Therefore , 16th term of the given arithmetic progression is 136 .

Find the volume of a box with the following measurements:

4: 20 cm3

5: 240 cm

Answers

Answer:

4: 20 cm3

Step-by-step explanation:

6 x 4 = 24

24 x 10 = 240

it is cubic since it is volume

Answer: 6

Step-by-step explanation:

4 x 6 = 24

24 x 10 = 240

So the total volume is 240, but without the units it could mean anything. 240 inches or cows, so we have to add cm, but this number could also mean any measurement of centimeters, length, area, perimeter, so we add the 3 to get

240cm3

the 3 is the symbol for cubed, meaning it's measuring the volume of a three dimensional area.

b) 10 - 20 – 45
c) -10 - 20 + 45
d) -10 – 20 - 45

Answers

Answer:

A.

Step-by-step explanation:

It's set up exactly as it is said. She starts with 10 points automatically so you would put:

10

Then it says that she lost 20 points. Losing is subtraction. You would add this to the equation:

10-20

Then it says she won 45 points. Winning is addition. You would add this to the equation:

10-20+45

This equation matches up with A. thus A. being the correct answer. If they ask for the answer, it is 35 by the way. Hope this helps!

a) 10 - 20 +45

Is known :

She started with 10 points.

In the first round she lost 20 points.

In the second round she won 45 points.

Asked :

Which of the following shows the changes in Anayah scores?

Childhood participation in sports, cultural groups, and youth groups appears to be related to improved self-esteem for adolescents (McGee, Williams, Howden-Chapman, Martin, & Kawachi, 2006). In a representative study, a sample of n = 100 adolescents with a history of group participation is given a standardized self-esteem questionnaire. For the general population of adolescents, scores on this questionnaire form a normal distribution with a mean of μ = 50 and a standard deviation of σ = 15. The sample of group-participation adolescents had an average of M = 53.8.
Does this sample provide enough evidence to conclude that self-esteem scores for these adolescents are significantly different from those of the general population? Use a two-tailed test with α = .05.

Answers

Testing the hypothesis, we can conclude that since the p-value of the test is 0.0114 < 0.05, which means that the sample provides enough evidence to conclude that self-esteem scores for these adolescents are significantly different from those of the general population.

At the null hypothesis, we test if the mean is the same of the general population, that is:

[tex]H_0: \mu = 50[/tex]

At the alternative hypothesis, we test if it is different, that is:

[tex]H_1: \mu \neq 50[/tex]

The test statistic is given by:

[tex]z = \frac{M - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

For this problem, the parameters are:

[tex]M = 53.8, \mu = 50, \sigma = 15, n = 100[/tex]

Then, the value of the test statistic is:

[tex]z = \frac{M - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{53.8 - 50}{\frac{15}{\sqrt{100}}}[/tex]

[tex]z = 2.53[/tex]

Two tailed test, so the p-value is P(|z| < 2.53), which is 2 multiplied by the p-value of z = -2.53.

Looking at the z-table, z = -2.53 has a p-value of 0.0057

2(0.0057) = 0.0114

The p-value of the test is 0.0114 < 0.05, which means that the sample provides enough evidence to conclude that self-esteem scores for these adolescents are significantly different from those of the general population.
