D=m/v so d=50/10=5
The density is 5g/ml
It might be ml^3 (5g/ml^3) but I don’t remember
Alliteration
how I remember is that the 2 L’s are together in the word, and the same letter is repeated in the sentence.
if that makes sense,
hope i’m not too late!!

Answer with explanation:</h2>
The confidence interval for population mean is given by :-
(1)
, where
= sample mean
z* = critical value.
SE = standard error
and
,
= population standard deviation.
n= sample size.
As per given , we have


n= 15
It is known that ring diameter is normally distributed.
By z-table ,
The critical value for 95% confidence = z*= 1.96
A 99% two-sided confidence interval on the true mean piston diameter :
(using (1))

[Rounded to three decimal places]
∴ A 99% two-sided confidence interval on the true mean piston diameter = (74.020, 74.022)
By z-table ,
The critical value for 95% confidence = z*= 1.96
A 95% lower confidence bound on the true mean piston diameter:
(using (1))
[Rounded to three decimal places]
∴ A 95% lower confidence bound on the true mean piston diameter= 74.020
2,400
20% of 3,000= 600
3,000 - 600= 2,400
