The two is in the hundreth place
Look at the number next to it, it's a five. Five rounds 2 to 3.
Your answer is 0.13
Answer: 38416
Step-by-step explanation:
The formula to find the sample size in a normally distributed population :-
, where
= Population standard deviation from the prior study.
z* = critical z-value , E = Margin of error.
As per given , we have
The scale readings are Normally distributed, with unknown mean m m and standard deviation σ = 0.01 grams.
E = ±0.0001
Critical z- value for 95% confidence interval : z* = 1.96
Substitute all values in formula , we get

Hence, the minimum sample size should be 38416 .
Answer: A, C, D
If you try plugging in a few different numbers into these equations, you will get only 1 result.

Answer:
The required probability is 0.0281
Step-by-step explanation:
Consider the provided information.
Air-USA has a policy of booking as many as 18 persons on an airplane that can seat only 17.
Studies have revealed that only 82% of the booked passengers actually arrive for the flight.
Therefore, the probability of a person arrive is 0.82
Find the probability that t if Air-USA books 18 persons, not enough seats will be available.
Probability that 18 persons arrive = 
Hence, the required probability is 0.0281
I think the answer might be A
