Answer:
0, 4, -4 and they may want you to mention formally all the kt multiples of .
Step-by-step explanation:
Let's do the second derivative of the function:
So now we want:
Then we have to include the zeros of the binomial () which as you say are +4 and -4, and also the zeros of , which include all those values of
So an extra one that they may want you to include is k = 0

The solution to the Questions are
- The alternate hypothesis demonstrates that there are two possible outcomes for the test.
- Decision rule: If z > 2.05 or z<-2.05, reject H0
- The two-tailed nature of the test is shown by the alternative hypothesis.
- The result of the test yields the following P-value: 0.0096
<h3>What is the alternate hypothesis?</h3>
(a)
The alternate hypothesis demonstrates that there are two possible outcomes for the test.
(b)
Here we have
(b)
Here the test is two-tailed. So for , the critical values of the z-test are -2.05 and 2.05.
Decision rule: If z > 2.05 or z<-2.05, reject H0
(c)
Test statistics will be
z=2.59
(d)
The two-tailed nature of the test is shown by the alternative hypothesis.
(e)
The result of the test yields the following P-value: 0.0096

Answer:
Step-by-step explanation:
(85+92+95+x)/4
=90
(272+x)/4
=90
90×4=360
272+x=360
x=360-272=88
so it's the lowest score
