Question

Computer interfacing based on series interfacing has been analyzed and comprehensively studied. Data
analysis in term of errors (variance and Standard deviation), accuracy and smoothing using computer based
statistical distribution have been learned and applications of statistical distribution (binomial, Normal and
Poisson) have demonstrated by solving problems
.b) Mangoes of weight X grams are packed in a carton by machine A by randomly using normal distribution
with mean  grams and standard deviation  grams.
Given that P (X < 140) = 0.99 and P ( X > 175) = 0.9 Calculate out the values of  and . [2 marks]
