RESULT & OBSERVATION The hypothesis for statistical testing must be written as Null hypothesis (H0) and Alternate (Research) hypothesis (H1) form. H0 1= There is no significant relationship between body height, foot length and knee height in both the sexes. H1 1= There is relationship between body height, foot length and knee height and are significant in both the sexes.
H0 2= Body height is equally estimated from both foot lengths and Knee height in both the sexes more accurately.
H1 2= Body height is best and more accurately estimated from knee height in both the sexes than with both foot lengths or vice a versa.

The total size of the subjects was 1000 out of which 500 males and 500 females.
The above five different parameters mean between the male and the female were compared using Z test. The Z test was applied because the total sample size was 1000. It was assured that the samples were collected from a normal population whose parameters were unknown.
Hence the Z test was applied as under:-
Z= (((x_1 ) ̅- (x_2 ) ̅))/√((〖σ_1〗^2/n_1 + 〖σ_2〗^2/n_2 ))
Where:
(x_1 ) ̅ = mean of sample 1/ group 1 i.e. male subject,
(x_2 ) ̅ = mean of sample 2/ group 2 i.e. female …show more content…

Table nos.2, 3 &4 depicts the descriptive statistics of body height, age, foot lengths and knee height in both males and females as well as in both genders respectively. The differences of the means of all variables except age were found to be higher and significant in males as compared to female counterpart. No significant difference was found in both males and females left and right foot length measurements.
Body height showed positive as well as significant correlation with both sided foot lengths and knee height (table no. 5). Males as compared to females presented more significant correlation of body height with all variables. Moreover in both males and females Knee height (0.74, p< 0.5 cm, rTEM < 0.84%, and R ≥ 0.98) (Table 11) and (inter-TEM < 0.65 cm, rTEM < 0.89%, and R ≥ 0.95)
