Two imaginary roots
Step-by-step explanation:
Given polynomial,
Apply hit and trial method to find zero
This polynomial has one factor is
We can find another factor
Real root
is always positive so it have no real roots
Roots are imaginary
has one real root and two imaginary roots

Answer:
F.) H0:μ=4.55, Ha:μ≠4.55
A.) H0:μ=115, Ha:μ<115
H0:μ=69 , Ha:μ>69
Step-by-step explanation:
The null and alternative hypothesis are used in hypothesis testing.
Generally, both hypothesis negatives each other, with the alternative being the opposite of the null hypothesis.
1)the mean value of the population is 4.55 ; the researcher aims to test if the mean value differs from thus value, hence, Alternative ; μ ≠ 4.55
2.) The mean resting heart rate is said to be 115 ; this is the null claim. The reaesrch aims to test if heart rate slows down with age. Hence, the alternative will be to show that mean rate lesser Than 115 as claimed (μ < 115)
3.) Theean height of the population is claimed to be 69. Researcher aims to test if some people within the population have mean height abive this said height. (μ > 69)
