I am assuming that the question you are asking is basically, "There are a total of 125 marbles and 50 red marbles.  What is the ratio of red marbles to the total number?"

If this is what you are asking, we begin by setting up the ratio of red marbles to all marbles.  This is 50:125, because there are 50 red marbles and a total of 125 marbles.

It may seem that we are done, but we are not finished yet.  In order to finish, we need to reduce the ratio.  It is clear that we can take 25 from both 50 and 125, so our new ratio is 2:5.  This ratio can not be reduced, so 2:5 is the final answer in simplest form.

A veterinarian collects data on the number of times race horses are raced during their careers. The veterinarian finds that the
SpyIntel [72]

Answer:

c. (12.12, 18.48)

Step-by-step explanation:

Hello!

The study variable is X: number of times a racehorse is raced during its career.

The average number is X[bar]= 15.3 and the standard deviation is S= 6.8 obtained from a sample of n=20 horses.

To estimate the population mean you need that the variable has a normal distribution, in this case, we have no information about its distribution so I'll assume that it has a normal distribution. With n=20 the most accurate statistic to use for the estimation is a Students-t for one sample, the formula for the interval is:

X[bar] ± t_{n-1;1-\alpha /2} * \frac{S}{\sqrt{20} }

t_{n-1;1-\alpha /2} = t_{19;0.975}= 2.093

[15.3 ± 2.093 * \frac{6.8}{\sqrt{20} }]

[12.12; 18.48]

Using a significance level of 95% you'd expect that the true average of times racehorses are raced during their career is included in the interval [12.12; 18.48].

I hope it helps!
