2.A city department has introduced a quality improvement program and has allowed employees to get credit for overtime hours when attending the meetings of their quality groups. The total number of overtime meeting hours, for each of the 26 pay periods in one year by now, were: 30, 100, 100, 96, 194, 163, 65, 41, 100, 43, 96, 100, 80, 42, 100, 75, 95, 65, 43, 163, 41, 41, 80, 114, 30, 114

(a) Find the mean of the overtime hours.

(b) Complete the table and find the variance and standard deviation.

3. The number of days the first 22 heart transplant patients at Stanford survived after their operation were: 3, 15, 20, 23, 26, 32, 32, 32, 46, 48, 48, 56, 64, 68, 69, 69, 70, 71, 71, 80, 85, 125

(a) Find the median.

(b) Find the 90𝑡ℎ90th percentile.

(c) Find the first and the third quartile.

(d) Is there any outlier in this data set?

(e) Construct a box plot.

4.The medical records of the 445 male diabetics patients reporting to a clinic during one year provide the following results:

Find the probability that:

(a) The age of the patients is above 40 and their parents are not diabetics.

(b) The age of the patients is above 40 or their parents are not diabetics.

(c) The age of the patients is above 40 given that their parents are not diabetics.

(d) The age of the patients is between 20 and 40 or their parents are diabetics.

If 𝐴=A=”The age of the patient is below 20” and 𝐵=B=”Patient’s parents are diabetics”.

(e) Are events A and B independent? Justify tour answer.

(f) Are events A and B mutually exclusive? Justify tour answer.

5. According to the Mendelian theory of inherited characteristics, a cross fertilization of related species of red- and white- flowered plants produces a generation whose offspring contain 25% red-flowered plants. Suppose that a horticulturist wishes to cross 7 pairs of the cross-fertilized species. Of the resulting 5 offspring, what is the probability that:

(a) Let 𝑋=X= the number of red-flowered plants. What is the probability distribution of 𝑋X?

(b) There will be no red-flowered plant.

(c) There will be 4 or more red-flowered plants.

(d) Find the expected value, variance and the standard deviation of 𝑋X.

6. The Colorall Paint factory uses “agent A” in the paint manufacturing process. There is an average of 3.45 particles of agent A in a cubic metre of the air emitted during the production process.

(a) Let 𝑋=X= the number of particles of agent A in a cubic metre of the air emitted. What is the probability distribution of 𝑋X?

(b) What is the probability that there will be five particles of agent A in a cubic metre of air emitted from the factory?

(c) What is the probability that there will be at least four particles of agent A in a cubic metre of air emitted from the factory?

(d) Find the expected value, variance and the standard deviation of 𝑋X.

The Community

Neighborhood people group ought to conform to government laws and household guidelines. For whatever length of time that they meet the necessities of these chances, everybody has equivalent open doors for an amazing duration. Individuals who are qualified and put forth a valiant effort for the network lead the network. Society depends on unrestrained choice, except if rules are watched and nobody is harmed. Rules and guidelines are intended to secure individuals of the general public so as to fabricate a protected and amicable network.

There are two fundamental kinds of network networks, networks characterized by geologically characterized networks and topographically various factors. Instances of geologically characterized networks are networks or neighborhoods. The assembled houses share a typical space. Nearby economies and local organizations are additionally viewed as a feature of the neighboring network. Individuals from the network are invested individuals in network wellbeing, and I am keen on this

What is a network? Parker characterizes the network as individuals who share a typical space or area, share a typical relationship, collaborate with one another, and are broadly utilized in the writing (Fritz, 1985). The people group comprises of common commitments and communications connecting people to foundations and relationship systems. In most topographical networks, there is a typical association and a pretty much free network. Schools, law requirement offices, and social government assistance offices are three instances of formal associations inside the network that are especially important for substance misuse. Guardians and understudy associations vary in structure, normal to most networks, and can assume a significant job in forestalling drug misuse. Local gatherings and individuals from the association cooperate to make, characterize, and tackle social issues by connecting with each other.

Procedures for network based sociological practice are talked about. With regards to social development of practical hypotheses, the job of sociologists in helping networks comprehend social issues has been broke down. When the network acknowledges young people ‘substance misuse issues, the hypothesis of control and partners’ affiliation can lead sociologists who wish to work with nearby pioneers to battle medicate misuse. Network association, fortify the association among guardians and different gatherings, bring down the network’s capacity to bear medicate misuse, assemble support for peer avoidance
