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.
Y=2x+3，when x is equal to 0，y is equal to 3, which means intercept is equal to 3
Answer:
denominator
Step-by-step explanation:
the upper part is numerator
so the lower is denominator
Answer:
Correct choice is A.
Step-by-step explanation:
We have to find about which of the given choices is the formula for the volume of a pyramid with base area B and height h.
We know that formula of volume of pyramid is given by:
Plug the given values
So the correct choice is A.
The volume of <span>a right square pyramid is
, where </span><span>
is basis area.
</span>
If the lengths of the sides of the base remain fixed and height
<span>is multiplied by a factor 10, than new height is
and the volume is
</span>
