NEW COURSE
GROUP "A"
Attempt any SIX Questions.
6x5=30
1. What do you understand by dispersion? Consider the following
data, which are sample of amino acid concentration (mg/100ml)
in anthropod hemolymph.
24.6, 24.8, 23.2, 25.7, 25.1, 23.9. Determine range, standard
deviation and coefficient of variation.
2. Define conditional probability. A manufacturing firm employs
two analytical plans for the design and development of a
particular product. For last seasons, both are used at varying
times. In fact plans 1 and 2 use for 40% and 60% of the
products respectively. The defect rate different for the two plans
as follows P(D/P1) = 0.01 and P(D/P2) =0.02 where P(D/Pi) is
the probability of defective product, given
i. if a product was
observed and found to be defective, what is the probability that
it was produced by plan 1?
3. State two assumptions needed for a binomial distribution to be
good model. The probability of a novice archer hitting a target
with any shot is 0.4. Given that the archer shoots six arrows,
find the probability that the target is hit at least twice.
4. Define briefly a normal distribution. The length of sweet pea
flower stems are normally distributed with mean 17.5 cm and
standard deviation 2.4 cm. find the probobiity that the length of
flower is more then 19.8 cm.
