Given data
97.4, 98.4, 99.9, 97.2, 96.1, 98.4, 96.3, 98.4
Arranging in ascending order we get,
{96.1, 96.3 97.2, 97.4, 98.4, 98.4, 99.9}
4) Mean = sum(Xi) / n
= (96.1+ 96.3+ 97.2+ 97.4+ 98.4+ 98.4+ 99.9)/ 7
= 97.67
5) Mode = most repeating value = 98.4 (as it is the only one which repeats twice)
6) Midrange value
= (high+low)/2
= (96.1 + 99.9)/2
= 98
7) median = 4th element of 7
= 97.4
8,9) variance = sum(Xi - x bar)/n
= {(96.1- 97.67)^2+ (96.3 - 97.67)^2+ (97.2 - 97.67)^2+ (97.4- 97.67)^2+ (98.4- 97.67)^2+ (98.4- 97.67)^2+ (99.9- 97.67)^2)/ 7
= 1.5249
standard deviation = sqrt(variance)
= sqrt(1.5249)
= 1.235
11)
u = 94.7, = 1.9
x = 100
We have,
Z = (x-u)/
Z = (100-94.7)/1.9
Z = 2.789
