Solution :
The normal body temperature of any human body is considered to be 98.6. But there is a constant debate about the body temperature of a long held standard to the body temperature.
It is given that :
Null hypothesis and alternate hypothesis :
And
n is given as = 180
Test statistics = 3.64
Prove = 0.018 < α = 0.05 (let reject null hypothesis for α = 0.05 )
Therefore, their results are statistically significant and the result is unlikely due to chance alone.
Answer:
25 unit
Step-by-step explanation:
See attachment for the missing figure.
Assuming the complete question is:
Side UY = 4z-1
Side UV = 5z+3
Perimeter of rectangle is given by:
2UY+2UV=P
2(4z-1)+2(5z+3)=84
8z-2+10z+6=84
18z+4=84
18z = 84 -4 =>
18z = 80
z= 4.45 unit
Side UV = 5z+3 => 5(4.45) + 3
Side UV ≈ 25 unit
SInce, Side UV = Side XY
Side XY≈ 25 unit
