Answer 1

Answer:

136.66=Mode answer hope it's helpful

Answer 2

Answer:

Here, N is 45, which is odd.Median ={(N+12)th observation} ={45+12}observation =23 th observationMedian =150Mean =∑(fi×xi)∑fi=705045=156.67Mode=3(Median)−2(Mean) =3(150)−2(156.67) =450−313.34 =136.6Here, N is 45, which is odd.Median =N+12th observation =45+12observation =23 th observationMedian =150Mean =∑(fi×xi)∑fi=705045=156.67Mode=3(Median)-2(Mean) =3150-2(156.67) =450-313.34 =136.6

Hence, the median is 150, the mean is 156.67 and the mode is 136.6.

hope it's correct and helpful for you
