Which area of Xcode provides controls to navigate breakpoints? CORRECT

Answer:

(a) [tex]\bar x_1 = 43.7[/tex]     [tex]\bar x_2 = 30.25[/tex]

(b) [tex]\sigma_1 = 16.93[/tex]    [tex]\sigma_2 = 7.14[/tex]

(c) Smoking increases the time to fall asleep

Explanation:

Solving (a): The sample mean of each group

Mean is calculated as:

[tex]\bar x = \frac{\sum x}{n}[/tex]

So, we have:

Smokers

[tex]n_1= 12[/tex] and

[tex]\bar x_1 = \frac{69.3 +56.0+ 22.1 +47.6+ 53.2+ 48.1+ 52.7 +34.4+ 60.2 +43.8 +23.2 +13.8}{12}[/tex]

[tex]\bar x_1 = \frac{524.4}{12}[/tex]

[tex]\bar x_1 = 43.7[/tex]

Non Smokers

[tex]n_2 = 15[/tex] and

[tex]\bar x = \frac{28.6 +25.1 +26.4 +34.9 +28.8 +28.4 +38.5 +30.2 +30.6 +31.8 +41.6 +21.1 +36.0 +37.9 +13.9}{15}[/tex]

[tex]\bar x_2 = \frac{453.8}{15}[/tex]

[tex]\bar x_2 = 30.25[/tex]

Solving (b): The standard deviation of each group

This is calculated as:

[tex]\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]

For smokers

[tex]n_1= 12[/tex]

So:

[tex]\sigma_1 = \sqrt{\frac{(69.3 -43.7)^2+(56.0-43.7)^2+..........+(13.8-43.7)^2}{12-1}}[/tex]

[tex]\sigma_1 = \sqrt{\frac{3152.04}{11}}[/tex]

[tex]\sigma_1 = \sqrt{286.5491}[/tex]

[tex]\sigma_1 = 16.93[/tex]

For non-smokers

[tex]n_2 = 15[/tex]

So:

[tex]\sigma_2 = \sqrt{\frac{(28.6 -30.25)^2+(25.1 -30.25)^2+..........+(13.9 -30.25)^2}{15-1}}[/tex]

[tex]\sigma_2 = \sqrt{\frac{713.2575}{14}}[/tex]

[tex]\sigma_2 = \sqrt{50.9469}[/tex]

[tex]\sigma_2 = 7.14[/tex]

Solving (c): Impact of smoking on time to sleep

In (b), we have:

[tex]\sigma_1 = 16.93[/tex] --- smokers

[tex]\sigma_2 = 7.14[/tex] --- non-smokers

Smokers have larger standard deviation (i.e. large variability) than non-smokers. This means that smokers require more time to fall asleep.

Answer:

In order to reduce the risk of accidents on the roads.

Explanation:

The special equipment is used when  testing eyesight for a driver's license in order to reduce the risk of accidents on the roads.

Explanation:

Answer:

0

Explanation:

The statement, print(8 % 4) will produce the output 0 ;

The print statement is an inbuilt function which is used to output a typed string or display result of a Mathematical calculation and so on.

The expression in the print statement gives 0;

8%4 means, the remainder when 8!is divided by 4 ; 8 /4 gives 2 without a remainder. Meaning that :

8%4 = 0

Hence, print(8 % 4) = 0

Answer:

1. Comment

2. Five (5).

3. Line.

4. Tuple; that

Explanation:

1. A comment is a human-readable description in the source code of a computer program. Thus, it's an annotation or description in the source code of a software program that is readable by humans.

2. Python has five (5) standard data types, these includes; number, string, list, dictionary and tuple.

3. A line contains items separated by commas and enclosed within square brackets i.e [ ]. Thus, it's simply an ordered collection of one or multiple data items.

4. A tuple consists of key-value pairs

that cannot be changed and use parentheses. For example, Newtuple = ("strawberry", "apple", "mango", "banana", "orange").

Answer:

random_number_file = open("1000 Random Number from 0 to 100.txt", 'r')

random_number_list = random_number_file.readlines()

print('random_number_list)

Explanation:

The name of the file containing the random integer text is ; "1000 Random Number from 0 to 100.txt"

The random_number_file variable stores the opened file ("1000 Random Number from 0 to 100.txt") using the open keyword and reads it ('r')

This file stored in the random_number_file variable is the read into a list by using the readlines() method on the random_number_file

Answer: Visibility timeout

Explanation:

The period of time during which the SQS queue prevents other consuming components from receiving and processing a message is known as the visibility timeout.

It is the length of time when a message will be hidden after such message has been grabbed by a consumer. It is essential as it prevents others from processing such message again.

Answer:

C. Byte pair encoding is an example of a lossless transformation because an encoded string can be restored to its original version.

Explanation:

Byte pair encoding is a form of encoding in which the most common pairs of consecutive bytes of data are replaced by a single byte which does not occur within the set of data.

For example, if we has a string ZZaaAb, it can be encoded if the pairs of string ZZ are replaced by X and the second pair by Y. So, our data now becomes XYAb.

To get our original data, that is decode it, we just replace the data with the keys X = ZZ and Y = aa thus allowing our original data to be restored.

Since our original string is restored without loss of data, it implies that byte pair encoding is an example of a lossless transformation because an encoded string can be restored to its original version.
