...must first be obtained. And so,
P(F) = P(FA) + P(FD) + P(FE)
= P(F|A)P(A) + P(F|D)P(D) + P(F|E)P(E)
= (0.6)(0.01) + (0.5)(0.01) + (0.8)(0.0005)
= 0.006 + 0.005 + 0.004
P(F) = 0.0114
Then,
__P(FD)__
P(D|F) = P(F)
= 0.005 / 0.0114
P(D|F) = 0.438596491
Therefore, the probability that one has Diabetes if one is severely fatigued is 0.439.

1. Mean, which shows the average level of satisfaction
2. Standard deviation, that shows the extent of dispersal of the **data** about the mean
3. Median, representing the middle value
4. Mode, giving the **data** that occurs most frequently.
The above are calculated for all the employees first and then for female and male employees separately. All **data** is calculated on a scale of 1 to 7 where 1 represents very poor and 7 as very good. The results are presented below:

...EBS101: **Statistical** Methods Assignment Sheet 2 For set A, a linear regression line of Y against X2 needs to be plotted. The regression line, alongwith the plotted **data**-points, is as follows-
The linear regression line passes through all points, and the value of the correlation coefficient is 1 (that is, perfect correlation). Thus, it is concluded that there is a perfect linear association between the given **data** sets.
For set B, a linear regression line of Y against X needs to be plotted. The regression line, along with the plotted **data**-points, is as follows-
The linear regression line lies close to most points, and (2.4, 2.6) is an anomaly. The value of the correlation coefficient is 0.96, which represents a fairly strong positive... ...

...Q1. Lets say that you find that there is a correlation of 0.95 between the population of a and the number of people who eat out frequently. Whatdoes this mean, if anything, about your chances of success if you locate your restaurant in a big city rather than in a smaller city?
A correlation of 0.95 between the population of a city and the number of people who eat out frequently suggests that there is a strong positive linear association between the population of a city and the number of people who eat out frequently. Thus, as the population of a city increases, the number of people who eat out frequently also increases. In other words, the number of people who eat out frequently will be higher in a big city compared to a smaller... Lets say...

...**statistics** in helping understand and in the process solve various issues. A common example can be seen with psychologists’ keen interest on how health is affected by stress. A focused **question** might involve the study of a specific psychological symptom and its impact on the health of the population. To assess whether the symptom is a good indicator of stress we need to measure the symptom and stress levels in a sample of individuals from the population. It is not immediately clear how we should go about collecting this sample, i.e. how we should design the study (Mandel, 2012).
The **data** sets that psychologists collect will usually consist of one more observations on one or more...
