Nicotine. Ultrafine particles that can be inhaled deep into the lungs. Flavoring such as diacetyl, a chemical linked to a serious lung disease. Volatile organic compounds.
Using the information given and the z-distribution, it is found that:
a) The point estimate of the population proportion is 0.5544.
b) The margin of error is: 0.0320.
c) The interval is: (0.5224, 0.5864).
d) The interpretation of the interval is: we are 95% sure that the true population proportion is between 0.5224 and 0.5864.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions has the bounds given by the rule presented as follows:

In which the variables used to calculated these bounds are listed as follows:
is the point estimate of the population proportion.
The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
From the sample, the sample size and the point estimate are given as follows:

The margin of error is given by:


M = 0.0320.
The interval is the point estimate plus/minus the margin of error, hence:
- Lower bound: 0.5544 - 0.0320 = 0.5224.
- Upper bound: 0.5544 + 0.0320 = 0.5864.

#SPJ1
Answer:
B
Explanation:
Plan A has a monthly payment of about $23 less and a total interest charge of $120 more than plan B.
Answer:
33 minutes
Explanation:
So, Copper went into the store at 4:40 p.m. then came out at 5:13 p.m.
One way to visualize this is to first count the minutes to 5:00 p.m. and then add the minutes after that. So, there is 20 minutes till 5:00 p.m., and then 13 minutes until 5:13 p.m. 20 + 13 = 33 minutes. This makes it easier to see how long Copper took in the store.
