The test statistic is
Step-by-step explanation:
We are interested in determining whether or not the proportion of the student who experience anxiety during the exam is significantly more than 80%.
At the null hypothesis, we test if the proportion is 80%, that is:
At the alternate hypothesis, we test if the proportion is more than 80%, that is:
The test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis,
is the standard deviation and n is the size of the sample.
80% is tested at the null hypothesis:
This means that
A random sample of 100 students was taken. Eighty-five of the student in the sample experienced anxiety during the exam.
This means that
The test statistic is
The test statistic is
Answer:
The formula to find the nth term of the given sequence is 54 ·
Step-by-step explanation:
The formula for nth term of an geometric progression is :
In this example, we have = 36 (the first term in the sequence) and
r = (the rate in which the sequence is changing).
Knowing what the values for r and are, now we can solve.
=
= 54 ·
Therefore, the formula to find the nth term of the given sequence is
54 ·
