Answer:
Option B) Do not reject null hypothesis, there is not enough evidence to support the claim that the proportion of homes in Oregon heated by natural gas is different from the 48% that the US Department of Energy reported.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 333
p = 48% = 0.48
Alpha, α = 0.01
Number of women belonging to union , x = 149
First, we design the null and the alternate hypothesis
This is a two-tailed test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from the table.
P-value = 0.273079
Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.
Thus, there is not enough evidence to support the claim that proportion of homes in Oregon that were heated by natural gas is different from what was reported.
B. Do not reject null hypothesis, there is not enough evidence to support the claim that the proportion of homes in Oregon heated by natural gas is different from the 48% that the US Department of Energy reported.

The result we would get when we simplify 5x/(x + 1) - (x - 4)/(x + 1), is 4.
<h3>How to Simplify an Expression?</h3>
Given the following expression:
5x/(x + 1) - (x - 4)/(x + 1), the first step to take is to find the common denominator.
The common denominator of the given expression is: (x + 1). Therefore, the expression would be simplified as shown below:
[1(5x) - 1(x - 4)] / (x + 1)
Evaluate the numerator
(5x - x + 4) / (x + 1)
Combine like terms in the numerator
(4x + 4) / (x + 1)
4(x + 1) / (x + 1)
Divide the numerator and denominator by (x + 1)
= 4
Therefore, the result we would get after simplifying the expression, 5x/(x + 1) - (x - 4)/(x + 1), is 4.
