Answer:
The minimum sample size that can be taken is of 14 dogs.
Step-by-step explanation:
The formula for calculating the minimum sample size to estimate a population mean is given by:

The <u>first step</u> is obtaining the values we're going to use to replace in the formula.
Since we want to be 95% confident,
.
Therefore we look for the critical value
.
Then we calculate the variance:

And we have that:

<u>Now</u> we replace in the formula with the values we've just obtained:

Therefore the minimum sample size that can be taken to guarantee that the sample mean is within 2 inches of the population mean is of 14 dogs.
Hi there!

Use slope formula to solve for the slope of the line:

Plug in points into the equation. We can use the points (0, -10) and (25, -5):

Isolate the variable by dividing both sides by 6:
t=144/6=24
The solution is t=24
Good luck!
