Q. What are quartiles, deciles, and percentiles? State the general
equation of computing the ith quartile, jth decile, and kth percentile.
Answer. Quartiles are measures
like the median. Median divides the series into two equal parts. Extending this
concept of median, we have quartiles. Quartiles can be classified into Q1, Q2
and Q3 This divided the series into four equal parts....... Deciles: The values
which divides an ordered data set into 10 equal parts. The 5th decile is the
median. The values of observations in a data set when arranged in an ordered
sequence can be divided into ten equal parts, using nine deciles......
Percentiles The values of observations in a data when arranged in an ordered
sequence can be divided into hundred equal parts using ninety nine percentiles,
Pi (i = 1, 2,…, 99). In general, the ith percentile is a number that has i% of
the data values at or below it and...........
Q. In a railway reservation office, two clerks are engaged in checking
reservation forms. On an average, the first clerk (A1) checks 55 per cent of
the forms, while the second (A2) checks the remaining. While A1 has an error
rate of 0.03 that of A2 is 0.02. A reservation form is selected at random from
the total number of forms checked during a day and is discovered to have an
error. Find the probabilities that it was checked by A1, and A2, respectively.
Answer.....
Q.The weekly wages of 2000
workmen are normally distributed with mean wage of Rs 70 and wage standard
deviation of Rs 5. Estimate the number of workers whose weekly wage are
a. between Rs 70 and Rs 71?
b. between Rs 69 and Rs 73
c. more than Rs 72, and
d. less than Rs 65
Answer.....
Q. A research organization claims that the monthly wages of industrial
workers in district X exceeds that of those in district Y by more than Rs 150.
Two different samples drawn independently from the two district yielded the
following results:
District X: x1 = 648, s12 = 120, and n1 = 100
District Y: x2 = 495, s22 = 140, and n2 = 90
Verify at 0.05 level of significance whether the sample results support
the claim of the organization.

Q. What do you mean by decomposition of a time series? State the
essential characteristics of the additive and multiplicative models of time
series analysis.
Answer. A time series is a
sequence of data points, measured typically at successive points in time spaced
at uniform time intervals........ Time series methods take into account
possible internal structure in the data, Time series data often arise when
monitoring..... The analysis of time series consists of two major steps:
Identifying the various factors or influences which produce the variations in
the time series, and Isolating, analysing and measuring the effect of these
factors independently, by holding other things constant. The purpose of
decomposition models is to break a time series into its components:
