The Data in the Table Represent the Amount of Pressure

question 37

Multiple Choice

The data in the table represent the amount of pressure (psi) exerted by a stamping machine (x) , and the amount of scrap brass shavings (in pounds) that are collected from the machine each hour (y) . Also shown below are the outputs from two different statistical technologies (TI- 83/84 Calculator and Excel) . A scatterplot of the data confirms that there is a linear association. Report the equation for predicting scrap brass shavings using words such as scrap, not x and y. State the slope and intercept of the prediction equation. Round all calculations to the nearest thousandth.

• A)scrap = - 2.019 + 2.134(pressure); slope = - 2.019 and the intercept is 2.134.
• B)scrap = 2.134 - 2.019(pressure); slope = - 2.019 and the intercept is 2.134.
• C)scrap = - 2.019 + 2.134(pressure); slope = 2.134 and the intercept is - 2.019.
• D)scrap = 2.134 - 2.019(pressure); slope = 2.134 and the intercept is - 2.019.

Definitions:

Cortex

The cortex is the outer layer of the cerebrum of the brain, involved in high-level functions such as consciousness, thought, emotion, reasoning, language, and memory.

Bipolar Cells

Nerve cells in the retina that are involved in the transmission of visual signals from the photoreceptors to the ganglion cells.

Optic Nerve

The nerve that transmits visual information from the retina to the brain, enabling sight.

Transduces Light

refers to the conversion of light into another form of energy, such as in the process of vision in the eyes where photoreceptor cells transduce light signals into neural signals.
