Step-by-step explanation:

Statistics can help decide the authorship of literary works. Sonnets by a certain Elizabethan poet are known to contain an average of new words (words not used in the poet's other works). The standard deviation of the number of new words is . Now a manuscript with 6 new sonnets has come to light, and scholars are debating whether it is the poet's work. The new sonnets contain an average of words not used in the poet's known works. We expect poems by another author to contain more new words, so to see if we have evidence that the new sonnets are not by our poet we test the following hypotheses.
H0 : µ = 8.88 vs Ha : µ > 8.88
Give the z test statistic and its P-value. What do you conclude about the authorship of the new poems? (Let a = .05.)
Use 2 decimal places for the z-score and 4 for the p-value.

a)The sonnets were written by another poet
b) There is not enough evidence to reject the null.

Answers

Complete question is;

Statistics can help decide the authorship of literary works. Sonnets by a certain Elizabethan poet are known to contain an average of 8.88 new words (words not used in the poet's other works). The standard deviation of the number of new words is 3. Now a manuscript with 6 new sonnets has come to light, and scholars are debating whether it is the poet's work. The new sonnets contain an average of 12.4 words not used in the poet's known works. We expect poems by another author to contain more new words, so to see if we have evidence that the new sonnets are not by our poet we test the following hypotheses.

H0 : µ = 8.88 vs Ha : µ > 8.88

Give the z test statistic and its P-value. What do you conclude about the authorship of the new poems? (Let a = .05.)

Use 2 decimal places for the z-score and 4 for the p-value.

a.What is z ?

b.The p-value is greater than ?

c. What is the conclusion? A)The sonnets were written by another poet or b) There is not enough evidence to reject the null.

Answer:

a) z = 2.87

b) P-value ≈ 0.0021

c) The sonnets were written by another poet

Step-by-step explanation:

We are given the hypothesis as;

Null hypothesis; H0 : µ = 8.88

Alternative hypothesis; Ha : µ > 8.88

We are also given;

Sample size; n = 6

Population Standard deviation; σ = 3

Sample mean; x¯ = 12.4

a) formula for z - value is;

z = (x¯ - µ)/(σ/√n)

z = (12.4 - 8.88)/(3/√6)

z = 2.87

b) we are given the significance value as α = 0.05.

From online p-value from z-score calculator attached and using z = 2.87; one tail distribution; α = 0.05, we have;

P-value = 0.002052

Approximating to 4 decimal places;

P-value ≈ 0.0021

c) The p-value is less than the significance level, thus we react the null hypothesis and conclude that the sonnets were written by another poet

A bacteria culture contains 1500 bacteria initially and doubles every hour. Find a function N that models the number of bacteria after t hours. Write out how many bacteria there will be for t = 0, 1, 2, etc. and think about how you are getting those values.

Answers

Answer: N(t) = (2^t)*1500

Step-by-step explanation:

Let's define the hour "zero" as the initial population.

So if N(t) is the number of bacteria after t hours, then:

N(0) = 1500.

Now, we know that the population doubles every hour, so we will have that after one hour, at t = 1

N(1) = 2*1500 = 3000

after two hours, at t = 2.

N(2) = 2*(2*1500) = (2^2)*1500

After three hours, at t = 3

N(3) = 2*(2^2)*1500 = (2^3)*1500

So we already can see the pattern, the number of bacteria after t hours will be:

N(t) = (2^t)*1500

How do you evaluate a division problem

Answers

Answer:

Step-by-step explanation:

Not wanting to be trite, i'd still suggest that you use a calculator for routine division. Round off your answer (quotient) to an appropriate number of decimal places.

For example, 2/3 comes out to 0.66666 ... (repeating decimal). You might want to round this off to 2 decimal places: 0.67.

The old fashioned "long division" is another method.

0 . 6

-----------

3 / 2 . 0 0 0

0. 0 0 0

---------------------

1. 8

and so on. You still need to round off the quotient to a suitable number of decimal places.

2(2x-1) = 4x-2

6x+14 +4x-2 = 10x+12

Answer:

P = 10x + 12

Step-by-step explanation:

The length of the rectangle is

L = 3x + 7

The width of the rectangle is

W = 2x - 1

The formula for perimeter of a rectangle is

P = 2L + 2W

Plug in the values for length and width and simplify.

P = 2(3x + 7) + 2(2x - 1)

P = 6x + 14 + 4x - 2

P = 10x + 14 - 2

P = 10x + 12

A. in a linear equation in x and y x is indepdendt so y depends on it

select all the equations on which the point (10, 0) lies. A. 5x+2y=15 B. 2x+4y=20 C. x+6y=10 D. 3x+3y=13 E. 4x+2y=20 F. 6x+y=50

Answers

Answer:

The answer to this problem is B, C, and E.

Step-by-step explanation:

The true equations are B. 2x+4y=20 and C. x+6y=10

How to determine the equations?

The point is given as (10,0)

This means that:

x = 10 and y = 0

Next, we test the options by substituting the above values.

So, we have:

A. 5x+2y = 15

5(10) + 2(0) = 15

50 = 15 ---- false

B. 2x+4y = 20

2(10) + 4(0) = 20

20 = 20 ---- true

C. x+6y=10

10 + 6(0) = 10

10 = 10 ---- true

D. 3x+3y=13

3(10) + 3(0) = 13

30 = 13 ---- false

E. 4x+2y=20

4(10) + 2(0) = 20

40 = 20 ---- false

F. 6x+y=50

6(10) + 0 = 50

60 = 50 ---- false

Hence, the true equations are B. 2x+4y=20 and C. x+6y=10
