a veterinary researcher takes an srs of 60 horses presenting with colic whose average age is 12 years. the average age of all ho
Ghella [55]

Answer:

The value 10 years is the population mean

Step-by-step explanation:

A sample consists of some observations drawn from the population, so a part or a subset of the population which in this case is the number of horses with colic.

A sample mean is the mean of the statistical samples while a population mean is the mean of the total population.

Thus, in this case, the sample mean is the mean age of the horses with colic while the population mean age is the mean age of all the horses found at the clinic.

Therefore, the mean age of 10 of the horses seen at the clinic would be the population mean.

I’m pretty confused on this question. Anyone know the answers?
Afina-wow [57]

Answer:

see explanation

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

• If m > 0, then the line slopes upwards from left to right ( increases )

• If m < 0, then the line slopes downwards from left to right ( decreases )

(a)

y + x = 3 ( subtract x from both sides )

y = - x + 3 ← in slope-intercept form

with m = - 1 ⇒ decreasing from left to right

(c)

y = 4x + 8 ← is in slope-intercept form

with m = 4 ⇒ increasing from left to right

the equation of a line in the form x = c represents a vertical line, where c is the value of the x-coordinates the line passes through

(b)

x - 5 = 0 ( add 5 to both sides )

x = 5 ← is a vertical line

the equation of a line in the form y = c represents a horizontal line, where c is the value of the y-coordinates the line passes through

(d)

\frac{y}{4} = - 6 ( multiply both sides by 4 )

y = - 24 ← is a horizontal line
