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.

The policy and art during the great depression were influenced by photojournalists like lange and walker through their photos which detailed the struggles of farmers and migrants.
Therefore, whenever photojournalists release photos people can actually know what farmers were passing through.

Answer:
Safety precautions in the heat transfer laboratory depend on the equipment that you will use.
Explanation:
The safety measures or precautions that an experimenter needs to bear in mind depends on the types of equipment he/she's using in experimenting. But, there are general precautions to consider.
There are three different ways to transfer heat, including convection, conduction, and radiation. <em><u>Convection</u></em><u> </u>pertains to the heat transfer between liquid or gas molecules moving circularly. Through that, their temperature and density are both affected. <em><u>Conduction</u></em><em> </em>and radiation are polarities. The heat transfer happened when two objects touched one another in conduction. On the other hand, <em><u>radiation</u></em> occurs when two objects do not touch each other.
Generally, precautions in performing these three experiments include the following:
- Careful handling of glassware to avoid cracking or breaking it.
- Avoid spilling the liquid or any content of the glassware.
- Do not touch any hot object.
- Use a hot pad to transfer hot objects from different places.
