Answer: The height of the pennant is 3 feet.
Step-by-step explanation:
We know that the area of a triangle is given by:-
Given , The base of the triangular pennant is 1.5 feet long.
Area of pennant = 2.25 square feet
Substitute these values in the formula we get,
Hence, the height of the pennant is 3 feet.
<h2>
Answer with explanation:</h2>
Let p be the population proportion .
Then,
According to the given information, we have
, since alternative hypothesis is two-tailed , so the hypothesis test is a two-tail test.
Since sample size is large (n> 30), we use z-test.
Let us consider 95% confidence i.e..
c) Critical value =
Sample proportion :
d) Test statistic :
i.e.
e) P-value (for two-tail) :
f) P-value is the probability value that we have falsely rejected the null hypothesis.
g) Since observed z-value (2.8) does not lie in critical interval (-1.96, 1.96), it means the null hypothesis is rejected.
An annotated bibliography includes the citation and a brief description of the source.
The citation can be made by plugging in information in an online citation website.
The description is 2 to 3 sentences about what type of source (primary or secondary) and how you used it (for the images, background info, etc).
