Answer:
First one.
Step-by-step explanation:
Answer:
We cannot determine the appropriate hypotheses to test this study because we are only given the data for the sample size and the population mean. Meanwhile, we need to know the data of the sample mean, the standard deviation and the level of significance before we can state the appropriate hypotheses for this test.
Step-by-step explanation:
Given that:
sample size n = 300
population mean μ = 35
The null hypothesis and the alternative hypothesis can be computed as follows:
Null hypothesis
Alternative hypothesis
The degree of freedom df = n -1
df = 300 - 1
df = 299
Answer:
Option b.
Step-by-step explanation:
Given that a repeated-measures experiment and a matched-subjects experiment each produce a t statistic with df = 10
A matched pair hypothesis test is conducted for the difference in the means for the pairs.
If 11 pairs i.e. 22 entries are compared thenwe have degrees of freedom = 11-1 =10
b. 11 for repeated and 22 for matched
is right answer.
Note: The degrees of freedom (DF) is:
DF = n - 1
where n is the number of paired observations.

Answer:
-16x³ - 36x² - 18x
Step-by-step explanation:
So here we just need to multiply these two functions together
f(x)*g(x) = (4x² + 3x)(-4x - 6)
Our first step is to foil: (4x²)(-4x) + (4x²)(-6) + (3x)(-4x) + (3x)(-6)
Then we can simplify each term by multiplying : -16x³ - 24x² - 12x² - 18x
We can than combine any like terms: -16x³ - 36x² - 18x
