<h3>I'll teach you how to solve 4/5 >-2/3d</h3>
------------------------------------------------
4/5 >-2/3d
Switch sides:
-2/3d < 4/5
Multiply both sides by -1:
(reverse the inequality)
(-2/3d)(-1) < 4/5 (-1)
Simplify:
2/3d > -4/5
Multiply both sides by 3:
3* 2/3d > 3(-4/5)
Simplify:
2d > -12/5
Divide both sides by 2:
2d/2 > -12/5/ 2
Simplify:
d > -6/5
Your Answer As A Fraction Is d > -6/5
Your Answer As A Decimal Is d > -1.2

Answer: (1.64,4.01)
Step-by-step explanation:
The confidence interval for the population variance is given by :-
Given : n= 69 ;
Significance level :
Using Chi-square distribution table ,
[by using chi-square distribution table]
Now, the 95% confidence interval for the standard deviation of the height of students at UH is given by :-
Hence, the 99% confidence interval for the population variance of the weights of all axles in this factory is (1.64,4.01).
