Answer:
z≈3.16
p≈0.001
we reject the null hypothesis and conclude that the student knows more than half of the answers and is not just guessing in 0.05 significance level.
Step-by-step explanation:
As a result of step 2, we can assume normal distribution for the null hypothesis
<em>step 3:</em>
z statistic is computed as follows:
z=
where
- X is the proportion of correct answers in the test (
) - M is the expected proportion of correct answers according to the null hypothesis (0.5)
- p is the probability of correct answer (0.5)
- N is the total number of questions in the test (40)
z=
≈ 3.16
And corresponding p value for the z-statistic is p≈0.001.
Since p<0.05, we reject the null hypothesis and conclude that the student knows more than half of the answers and is not just guessing in 0.05 significance level.
one term is monomial
two terms are binomials
three terms are trinomials
each term is separated by a + or - sign
so......6 has only one term ......it is a monomial
There are 91 in total. Since there are 21 red cars, it would give you 21/91. Around a 23.07% chance.
Constant is otherwise called term independent. It should not contain any other letters.
So, a constant without a variable best describes a constant.
