The sample size of 36 will produce the widest 95% confidence interval when estimating the population parameter option (b) is correct.
<h3>What are population and sample?</h3>
It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.
We have:
A sample has a sample proportion of 0.3.
Level of confidence = 95%
At the same confidence level, the larger the sample size, the narrower the confidence interval.
As we have a 95% confidence interval the sample size should be lower.
The sample size from the option = 36 (lower value)
Thus, the sample size of 36 will produce the widest 95% confidence interval when estimating the population parameter option (b) is correct.

(9-15)/(-2+4)= -6/2 = -3
-3 is the slope
The simplified form of the given expression is -18. The correct option is the third option- -18
<h3>Simplifying an expression</h3>
From the question, we are to simplify
|3-10| - (12 ÷ 4 + 2)²
Simplifying
|3-10| - (12 ÷ 4 + 2)²
|-7| - (3 + 2)²
7 - (5)²
7 - 25
= -18
Hence, the simplified form of the given expression is -18. The correct option is the third option- -18

Answer:
Step-by-step explanation:
Let's solve your inequality step-by-step.
−5(w+4)+8<−42
Step 1: Simplify both sides of the inequality.
−5w−12<−42
Step 2: Add 12 to both sides.
−5w−12+12<−42+12
−5w<−30
Step 3: Divide both sides by -5.
