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. What is z ?
b. The p-value is greater than ?
c. What is the conclusion?
a)The sonnets were written by another poet
b) There is not enough evidence to reject the null.
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

Sine and Cosine of any angle will always give a number less than 1. Why? (*HINT* Think about fractions and how Sine is oppositehypotenuse and Cosine is adjacenthypotenus )
Answer:
Hope this helped!
Step-by-step explanation:
The most easiest way to understand this is by considering a simple right angled triangle:-
For any right angled triangle
sin(theta)=perpendicular/hypotenuse
cos(theta)=base/hypotenuse
Since hypotenuse is the largest side so neither sin nor cos could be larger than 1.

Please describe a situation where you would use Excel and please describe the growth mindset needed to learn and understand.
A growth mindset is an idea that people are born with certain characteristics and can't change. A growth mindset allows a person to believe they can change themselves, and that abilities and intelligence can be developed over time. A growth mindset helps you learn that mistakes are stepping stones and that you aren't defined as some characteristic (like "dumb").

What is the inverse operations of the equation shown n+4=
Answer:
i aint never seen two pretty bestfriends
Step-by-step explanation:
The line y+2x=b is perpendicular to a line that passes through the origin. If the two lines intersect at one point (k+2,2k), what is the value of k?
Answer:
The line y+2x=b is perpendicular to a line that passes through the origin. If the two lines intersect at the point (k+2,2k)
Step-by-step explanation:
that should be right
The value of k is 2/3.
We have,
To determine the value of k, we need to find the equation of the line passing through the origin that is perpendicular to the line y + 2x = b.
The given line, y + 2x = b, can be rewritten in slope-intercept form
(y = mx + c) by solving for y:
y = -2x + b
Since the line passing through the origin is perpendicular to this line, its slope will be the negative reciprocal of the slope of the given line.
The given line has a slope of -2, so the perpendicular line will have a slope of 1/2.
Using the point-slope form (y - y1 = m(x - x1)) with the point (k + 2, 2k), we can write the equation of the perpendicular line passing through the origin as:
y - 0 = (1/2)(x - 0)
y = (1/2)x
To find the value of k, we equate the y-values of the two lines at the point of intersection:
(1/2)x = 2k
x = 4k
Since the x-coordinate of the point of intersection is k + 2, we can set it equal to 4k and solve for k:
k + 2 = 4k
2 = 3k
k = 2/3
Therefore,
The value of k is 2/3.

In the equation y=kx, which variable is the constant of proportionality?
Answer:the variable k is the constant of proportionality
Step-by-step explanation:
This can be proven when the equation is used to find different values of y. To find these different values, the x variable is substituted for different values while the k value stays the same. hope this helps!!

What is the slope?
Answer:
3
Step-by-step explanation:
In a slope intercept linear equation, the slope is always the number in front of the x value in an equation like y = mx + b.
So the slope is the 3 in front of the x value.
Priya and Joe travel the same 16.8 km route. Priya starts at 9.00 am and walks at a constant speed of 6 km/h Joe starts at 9.30 am and runs at a constant speed. Joe overtakes Priya at 10.20 am At what time does Joe finish the route?
Answer:
12:05 PM
Step-by-step explanation:
Priya started at 9:00 AM.
Speed of Priya = 6 km/hr
Joe started at 9:30 AM.
Time at which Joe overtakes Priya = 10:20 AM
Total time taken by Priya = 1 hour 20 min = [tex]\frac{4}{3}\ hr[/tex]
Total time taken by Joe = 50 min = [tex]\frac{5}{6}\ hr[/tex]
Distance traveled by Priya and Joe is same.
Formula for distance is:
[tex]Distance =Speed\times Time[/tex]
Distance covered by Priya = [tex]6 \times \frac{4}{3}[/tex] km
Let speed of Joe = [tex]S[/tex] km/h
Distance covered by Joe = [tex]S \times \frac{5}{6}[/tex]
[tex]S \times \dfrac{5}{6} = 6 \times \dfrac{4}{3}\\\Rightarrow S =\dfrac{48}{5}\ km/hr[/tex]
Total distance to be covered = 16.8 km
Total time to be taken by Joe =
[tex]\dfrac{16.8}{\frac{48}5} = \dfrac{16.8\times 5}{48} = \dfrac{84}{48} = 1.75\ hours[/tex]
1.75 hours mean 1 hour and 45 minutes.
Finishing time at which Joe finishes = 9:30 AM + 1 hour 45 minutes = 12:05 PM
