Answer:
95% confidence interval of the mean level of random exposure in tombs in the region.
(2746.868 , 4191.132)
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given sample size 'n'= 12
Mean of the sample x⁻ = 3,469
and standard deviation of the sample 's' = 1,135
<em>95% confidence intervals are determined by</em>
Degrees of freedom = n-1 = 12-1= 11
<u><em>Step(ii)</em></u>:-
<em>95% confidence intervals are determined by</em>
( 3469-722.132 , 3469 +722.132)
(2746.868 , 4191.132)
Answer:
34.6 units
Step-by-step explanation:
Given data
A (-5, -5), B (3, 4)
distance is
B (3, 4), C (3, -5)
C (3, -5), A (-5, -5)
Hence the perimeter
= 12.80+9+12.80
=34.6 units
