Answer:

**Answer:**

The 98 percent confidence interval for the population mean is between 27.85 and 29.75 subjects.

**Step-by-step explanation:**

We have that to **find **our level, that is the subtraction of 1 by the confidence interval divided by 2. So:

**Now**, we have to find z in the Ztable as such z has a pvalue of .

So it is z with a pvalue of , so

**Now**, find M as such

In which is the standard deviation of the population and n is the size of the sample.

The **lower end** of the interval is the mean subtracted by M. So it is 28.8 - 0.9488 = 27.85 subjects.

The **upper end** of the interval is the mean added to M. So it is 28.8 + 0.9488 = 29.75 subjects.

The 98 percent confidence interval for the population mean is between 27.85 and 29.75 subjects.

A. 1/14

B. 1/27

C. 13/14

D. 13/27

E. 14/27

The **probability** that the person** chosen** is a **boy** is 14/27.

Number of girls = 13

Number of boys = 14

Total students = 27

**Probability** is a** measure **of the** likelihood **of **occurrence** of an** event**.

**P(event) = Favorable outcomes / total outcomes**

Favourable outcomes = 14 because there are 14 boys

Total outcomes =27

So, the** probability **that the person** chosen** is a** boy **will be given by:

P(boy)=14/27

So, the **probability** that the person** chosen** is a **boy** is 14/27.

Hence, the **probability** that the person** chosen** is a **boy** is 14/27.

**Answer:**

E

**Step-by-step explanation:**

It's E because you have to add 13 and 14 and as you can see there's 14 boys so it's E.

Gary was on the Ferris wheel for a total of 36 minutes, calculated by subtracting the **time **he got on (2:40 P.M.) from the time he got off (3:16 P.M.).

To find out how long Gary was on the Ferris wheel, we need to **calculate **the difference in time from when he got on the ride to when he got off. He got on at 2:40 P.M. and got off at 3:16 P.M. To calculate the time difference, we first convert the times to a 24-hour format. So, 2:40 P.M. is 14:40 and 3:16 P.M. is 15:16.

Next, we subtract the starting time from the ending time. The calculation is as follows:

15:16 - 14:40 = 0:36

So, Gary was on the Ferris wheel for 36 minutes.

#SPJ12

**Answer:**

2:40 to 3:16

2:40 to 3 is 20 min

3 to 3:16 is 16 min

20+16=36

So, Gary was on the ride for 36 minutes!

**Answer:**

0.28

**Step-by-step explanation:**

For a certain breed of dog,

OFFSPRING OF A BLACK DOG:

Is black = 0.6 Is brown = 0.4

OFFSPRING OF A BROWN DOG:

Is black = 0.2 Is brown = 0.8

**If REX is a brown dog of this breed, what is the probability that his grand puppy will be black?**

The probability that his grand pup will be black = Probability that his black pups produce black pups + the probability that his brown pups produce black pups.

The probability that his black pups produce black pups:

0.2 × 0.6 = 0.12

The probability that his brown pups produce black pups:

0.8 × 0.2 = 0.16

The probability that his grand pup will be black = 0.12 + 0.16 = 0.28

The probability that the grand-pup of a brown dog (like Rex) will be black is calculated by multiplying the probability that a brown dog will produce a black offspring (0.2) by the probability that a black dog will produce a black offspring (0.6). This results in a probability of 0.12, or 12%.

In this problem, you're looking at the **probability** of a twice-removed descendent (a grand-pup) being a certain color, given the starting color of the ancestor (Rex). Since the color of the offspring is dependent on the color of the parent, this is a **conditional probability** problem.

The probability that the offspring of a brown dog will be black is 0.2. If that dog is black, the probability of its own offspring being black is 0.6. So, you multiply those probabilities together to find the probability that a brown dog will have a black grandpup, which is 0.2 * 0.6 = 0.12, or 12%. Therefore, the **probability** that Rex's grandpup will be black is **12%**.
