Answer:
a
The null hypothesis is
The alternative hypothesis is
b
c
The decision rule is
Reject the null hypothesis
d
The conclusion is
There is no sufficient evidence to conclude that the variance of the immune response is equal to 1.9.
Step-by-step explanation:
From the question we are are told that
The variance is
The sample size is n = 30
The sample variance is
The level of significance is
The null hypothesis is
The alternative hypothesis is
Generally the test statistics is mathematically represented as
=>
=>
Generally from the degree of freedom is mathematically represented as
=>
=>
Generally from the chi distribution table the critical value of at a degree of freedom of
is
=>
Gnerally from the values obtained we see that
hence
The decision rule is
Reject the null hypothesis
The conclusion is
There is no sufficient evidence to conclude that the variance of the immune response is equal to 1.9.
Answer: OPTION B.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
Given:
You can identify that its slope is:
By definition, the slope can be calculated with this formula:
Then, in order to find the slope of g(x), you can pick the points (2,-8) and (6,4) and say that:
So, substituting these values into the formula, you get:
If you subtract the slopes, you get that the positive difference between them, is:
