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:

algorithm.

Explanation:

An algorithm can be defined as a standard formula or procedures which comprises of set of finite steps or instructions for solving a problem on a computer. The time complexity is a measure of the amount of time required by an algorithm to run till its completion of the task with respect to the length of the input.

Furthermore, the processing symbols and their functions used in developing an algorithm are oval (start or stop), diamond (decision-making), circle (on-page connector), parallelogram (input and output), rectangle (calculation), arrow (flow or direction) and pentagon (off-page connector).

Some of the characteristics of an algorithm include the following;

I. An algorithm can be written using pseudocode. A pseudocode refers to the description of the steps contained in an algorithm using a plain or natural language.

II. An algorithm can be visualized using flowcharts. A flowchart can be defined as a graphical representation of an algorithm for a process or workflow.

In conclusion, an algorithm is a sequence of precise instructions which result in a solution​ for solving problems using a computer system.
