On a given day, the proportion of workers from Company B who purchase a coffee from the company cafeteria is 0.62 and the propor

tion of workers from Company C who purchase a coffee from the company cafeteria is 0.71. A random sample of40 workers was selected from Company B and another random sample of 40 workers was selected from Company C. The proportion of workers from Company B who purchased coffee was pˆB=0.70 and the proportion of workers from Company C who purchased coffee was pˆC=0.75.
What is the correct unit of measure for the mean of the sampling distribution of pˆB−pˆC ?

Answer:

The mean of a sampling distribution does not have units.

Explanation:

Given that:

P(B) = 0.62

P(C) = 0.71

pˆB = 0.70

pˆC = 0.75

The expression: pˆB−pˆC

Denotes the difference in means of the sample distribution:

The proportions pˆB = 0.70 and pˆC = 0.75 are determined by (number of employees who bought coffee / total number of employees). The aforementioned ratio will have no units due to the division.

in the following poem by gregory pardlo (published in 2007), the speaker describes watching children playing double dutch—a vers
Fittoniya [250]

Hello. You overlooked including the poem related to the inquiry. The poem reads:

"The girls turning double-dutch

bob weave like boxers pulling

punches, shadowing each other,

sparring across the slack cord

casting parabolas in the air. They

whip quick as an infant's pulse

and the jumper, before she

enters the winking, nods in time

as if she has a notion to share,

waiting her chance to speak. But she's

anticipating the upbeat

like a bandleader counting off

the tune they are about to swing into.

The jumper stair-steps into mid-air

as if she's jumping rope in low-gravity,

training for a lunar mission. Airborne a moment

long enough to fit a second thought in,

she looks caught in the mouth bones of a fish

as she flutter-floats into motion

like a figure in a stack of time-lapse photos

thumbed alive. Once inside,

the bells tied to her shoestrings rouse the gods

who've lain in the dust since the Dutch

acquired Manhattan. How she dances

patterns like a dust-heavy bee retracing

its travels in scale before the hive. How

the whole stunning contraption of girl and rope

slaps and scoops like a paddle boat.

Her misted skin arranges the light

with each adjustment and flex. Now heather-

hued, now sheen, light listing on the fulcrum

of a wrist and the bare jutted joints of elbow

and knee, and the faceted surfaces of muscle,

surfaces fracturing and reforming

like a sun-tickled sleeve of running water.

She makes jewelry of herself and garlands

the ground with shadows."

Answer and Explanation:

Similes and metaphors serve as literary devices that enhance and personalize the narrative in a poetic manner through analogies. A simile draws comparisons between unrelated elements to create novel interpretations, while a metaphor links disparate items with a shared trait.

The author likens the girls' rope activities to abstract and complex actions that require great precision, strength, and concentration.

These figures of speech appear in lines such as:

"The girls turning double-dutch

bob weave like boxers pulling

punches, shadowing each other,

sparring across the slack cord

casting parabolas in the air. They

whip quick as an infant's pulse

and the jumper, before she

enters the winking, nods in time

as if she has a notion to share,

waiting her chance to speak. But she's

anticipating the upbeat

like a bandleader counting off

the tune they are about to swing into."

illustrate a brief distinction between accidents and risky behaviours and give one relevant example for each/4909263/cdd31c2e?ut
vovikov84 [265]

The primary difference between an accident and risky behavior lies in predictability: accidents are generally unforeseeable or difficult to anticipate, whereas risky behaviors are actions taken with awareness of potential dangers.
<span>For instance, someone slipping and falling while climbing stairs is an accident since the person doesn't foresee this occurring.
<span>On the other hand, engaging in alcohol consumption despite knowing it might lead to problems, or skipping class deliberately with awareness of consequences, exemplify risky behaviors.</span></span>

Elenna [298]

Answer:

False.

Explanation:

Dr. Keyes' intended study involves two variables (pets and happiness), aiming to establish a cause-and-effect relationship: as pet ownership increases (cause), so does individual happiness (effect). Thus, it can be concluded that Dr. Keyes is not conducting a correlational study.

This is because correlational studies look to identify relationships between two variables but cannot validate causative linkages.
