ANSINER:-(a) Let x be the number of inclusions in a cubic centimeterr=2.5", then "=>lambda=2.5 xx1000=2500{:[mu=lambda],[=2500],[sigma=sqrt2500],[sigma^(2)=2500]:}{:[=2500],[sigma=sqrt2500=50quad" Here mean "=2500","" standard deviation "=50]:}(b) The probability that fewer than 2600 inclusions in a cubic centimeter can be calculated as{:[P(x < 2600)=P(x_(a) < 2600-0.5)],[=P((x_(a)-r)/(sigma) < (2599.5-2500)/(sqrt2500))],[=P(z < 1.99)],[=0.9767]:}[Ha is adjusted no. of success is 2599.5 )(C) The probability that more than 2400 inclusions in a kel{:[P(x ...
