question 45

Multiple Choice

The following MINITAB output display presents the results of a hypothesis test for the difference $\mu _ { 1 } - \mu _ { 2 }$ between two population means.
$The following MINITAB output display presents the results of a hypothesis test for the difference \mu _ { 1 } - \mu _ { 2 } between two population means. Difference = \operatorname { mu } ( \mathrm { X } 1 ) - \operatorname { mu } ( \mathrm { X } 2 ) Estimate for difference: - 26.338 95 \% CI for difference: ( - 47.152 , - 5.524 ) \mathrm { T } -Test of difference = 0 ( vs not = ) : T-Value = - 2.480133 \mathrm { P } - Value = 1.979112 \quad \mathrm { DF } = 23 How many degrees of freedom are there for the test statistic? A) 22 B) 26.338 C) 23 D) 1.979112$
Difference $= \operatorname { mu } ( \mathrm { X } 1 ) - \operatorname { mu } ( \mathrm { X } 2 )$
Estimate for difference: $- 26.338$
$95 \%$ CI for difference: $( - 47.152 , - 5.524 )$
$\mathrm { T }$ -Test of difference $= 0 ($ vs not $= ) :$ T-Value $= - 2.480133$
$\mathrm { P } -$ Value $= 1.979112 \quad \mathrm { DF } = 23$
How many degrees of freedom are there for the test statistic?

Definitions:

Phospholipid Bilayer

A fundamental structure in all cell membranes, consisting of two layers of phospholipids, which provides a barrier that marks the boundaries of a cell.

Selectively Permeable

A property of cell membranes that allows certain molecules or ions to pass through it by means of active or passive transport, while blocking others.

Transmembrane Proteins

Proteins that span across the cell membrane, facilitating various functions such as transport and signaling.

Cytosol

The liquid component of the cytoplasm, in which organelles, proteins, and other cell structures are suspended, facilitating intracellular transport and biochemical reactions.
