Answer:
The p -value for the hypothesis test is 0.003.
Step-by-step explanation:
In this case, a paired <em>t</em>-test would be used to determine whether the drug increases blood pressure.
The hypothesis can be defined as follows:
<em>H</em>₀: The drug has no effect on blood pressure, i.e. <em>d </em>= 0.
<em>Hₐ</em>: The drug increases blood pressure, i.e. <em>d </em>> 0.
The information provided is:
The test statistic is:
The degrees of freedom of the test is:
The <em>p</em>-value of the test is:
*Use a <em>t</em>-table.
Thus, the p -value for the hypothesis test is 0.003.
Correct composition of ( f o g)(1) is option A i.e. (ƒ ∘ g)(1) = 49
<h3>What are functions ?</h3>- In mathematics, a function from a set X to a set Y assigns exactly one element of Y to each element of X.
- The sets X and Y are referred to together as the function's domain and codomain, respectively.
- A function connects an input with an output.
- It works like a machine, having an input and an output.
- Furthermore, the input and output are linked in some way.
f(x) = 5 – x + 1
g(x) = -3x
a) ( f o g )(1) = 49
f(g(1)) = 49
5 * - - (-3) + 1 = 45 +3+1 = 49
it is true
all the other options are not equal to the given answer .
