Answer:

Step-by-step explanation: I choose d because if you notice there are only 33 marbles in Bag F and Bag F-number of marbles is equal to 1/3 marbles = 11/33 marbles and Bag G contains only 11 marbles which are how many marbles there are in all bags.

Answer:

The probability of randomly selecting a blue marble from bag F is 1/3

Step-by-step explanation:

Let's logically work this out:

Bag G has 33 marbles.

Bag F has 11 marbles.

Each bag is mentioned to have 11 blue marbles, so that means there is a 1/3 chance of picking a blue marble from bag F and a 1/1 (100%) chance of picking a blue marble from bag G.

A is incorrect because the chance of picking a marble from bag G (about 33%) is less than bag F (100%).

B is incorrect because the probability is 1/3, not 1/1. If it said bag F, it would be correct, however it is not so.

C is incorrect because, as mentioned before, 33% is not larger than 100%. It specifically says bag F has a greater chance, so this isn't correct.

D IS correct not only because it's the last one left, but because 11/33 (blue marbles to all marbles in the bag) is equal to 1/3 when simplified.

Kitty [74]

2.45 cm= 1 in. so 100 cm must equal 39.37 in. because you already know 2.45 cm equals 1 inch and 1 metre equals 100 cm and 1 metre is equal to 39.37.

Hunter-Best [27]

Answer:

The 68% confidence interval for the population proportion of college seniors who plan to attend graduate school is (0.16, 0.24).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

A recent survey showed that among 100 randomly selected college seniors, 20 plan to attend graduate school and 80 do not.

This means that $n = 100, \pi = \frac{20}{100} = 0.2$

68% confidence level

So $\alpha = 0.32$ , z is the value of Z that has a pvalue of $1 - \frac{0.32}{2} = 0.84$ , so $Z = 0.995$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2 - 0.995\sqrt{\frac{0.2*0.8}{100}} = 0.16$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2 + 0.995\sqrt{\frac{0.2*0.8}{100}} = 0.24$

The 68% confidence interval for the population proportion of college seniors who plan to attend graduate school is (0.16, 0.24).
