Q.No.2. A study of the effect of smoking on sleep patterns is conducted. The measure observed is the time, in minutes, that it takes to fall asleep. These data are obtained: [3] Smokers:69.3 56.0 22.1 47.6 53.2 48.1 52.7 34.4 60.2 43.8 23.2 13.8 Non Smokers: 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
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.

I just need some help working out this Java code! I can list the instructions below:
Modify the CountSpaces program so that contains a String that holds your favorite inspirational quote. Pass the quote to the calculateSpaces method and return the number of spaces to be displayed in the main method.
We're given this to start however I have been struggling as there are two classes and it's been confusing me. Thanks so much for any help! All good and God Bless!
public class CountSpaces
{
public static void main(String[] args)
{
// write your code here
}
public static int calculateSpaces(String inString)
{
// write your code here
}
}
Answer:
public class CountSpaces
{
public static void main(String[] args)
{
String quote = "The concept of infinity is meaningless inside of an insane human mind.";
int nrSpaces = calculateSpaces(quote);
System.out.println("Nr spaces in your quote is " + nrSpaces);
}
public static int calculateSpaces(String inString)
{
int count = 0;
for (int i = 0; i < inString.length(); i++) {
if (inString.charAt(i) == ' ') {
count++;
}
}
return count;
}
}
Explanation:
In this example there is only one class, and since all methods are static the true concept of the class is not even being used.

Suppose a large group of people in a room were all born in the same year. Consider the following three algorithms, which are each intended to identify the people in the room who have the earliest birthday based on just the month and day. For example, a person born on February 10 is considered to have an earlier birthday than a person born on March 5. Which of the three algorithms will identify the correct people?
I. All the people in the room stand up. All standing people form pairs where possible, leaving at most one person not part of a pair. For each pair, the person with the earlier birthday remains standing, while the other person in the pair sits down. If there is a tie, both people sit down. Any individual not part of a pair remains standing. Continue doing this until only one person remains standing. That person has the earliest birthday.
II. All the people in the room stand up. All standing people form pairs with another standing person that they have not previously been paired with where possible, leaving at most one person not part of a pair. For each pair, the person with the earlier birthday remains standing, while the other person in the pair sits down. If there is a tie, both people in the pair remain standing. Any individual not part of a pair remains standing. Continue doing this until only one person remains standing or all persons standing have the same birthday. Anyone still standing has the earliest birthday.
III. Beginning with the number 1, ask if anyone was born on that day of any month. Continue with the numbers 2, 3, and so on until a positive response is received. If only one person responds, that person has the earliest birthday. If more than one person responds, determine which person was born in the earliest month, and that person or those persons have the earliest birthday.
Answer:
II is correct.
Explanation:
Algorithm is a computer program which solves complex problems within minutes. The algorithms has different variants which are used according to user demand. In the given scenario the choice no II is correct. All standing people can form a pair with another standing person and the person standing in the last will have the earliest birthday.

с
Customers are likely to spend less time listening to information not relevant to their issue.
D
Customers will be unable to mistakenly select the incorrect department for their particular issue.
Answer:
The company will be able to provide human representative for any incoming call
Explanation:
The upgrade of a system is meant to resolve identified issues in an initial system and given that the available human representative is usually less than the number of incoming call at a given time, due to a constant drive for a larger customer base, we have;
The upgraded system will provide technologies such that human representative will not be required for some inquiries, customers will listen to mainly relevant information with regards to their issues and customers will be properly directed to the correct department that are concerned with their current issue
Therefore, the LEAST likely goal of the upgraded system from among the options and therefore the least likely to be provided by the upgrade is the company will be able to provide human representative for any incoming call
