Step-by-step explanation:
35 49 51 54 65 51 52 47 87 37 46 33 39 44 39 64 94 34 30 48
is the sample given
From the above we can find
Mean =sum of all observations /20
=
Variance =
Std deviation= square root of variance
= 16.424
Population estimate for mean = 49.95
Population estimate for std dev =
=3.673
The value that separate 50% top form 50% bottom is the median
Median is the middle value after arranging in ascending order
=average of 47 and 48 = 47.5
Proportion of atleast 60 = 2/20 = 0.1
