Answer:
A)
a) H0: ptrue < 0.7; Ha: ptrue = 0.7
B)
d) 0.64
C)
b) No
Step-by-step explanation:
Hypothesis is a technique which is used to test the event against an alternative hypothesis. The null hypothesis is set as a basis which is tested against an alternative hypothesis to make a conclusion. This null hypothesis is analysed against a probability using significance level and then a conclusion is made to accept or reject the null hypothesis.
Factorize the polynomials individually;
q²-7q-8= (q-8)(q+1) <-- denominator
q²+3q-4= (q-1)(q+4)
When a number is divided by 0, it becomes indefinite (creating a hole in the graph).
(q-8)(q+1)=0
q=8
q=-1
Therefore, the second option.
