Answer: B) [tex]H_0:\mu=9.3[/tex]
[tex]H_1:\mu\neq9.3[/tex]
Step-by-step explanation:
The given claim : [tex]\mu=9.3[/tex] which contains equals to sign.
The complement of the "equal" sign is "not equal to" sign.
So the complement of the above statement will be :-
[tex]\mu\neq9.3[/tex]
Since we know that the null hypothesis always contains the equals signa , so the null hypothesis for the given claim will be:_
[tex]H_0:\mu=9.3[/tex]
Also, the alternative hypothesis is complement of null hypothesis , so the alternative hypothesis for the given claim:-
[tex]H_1:\mu\neq9.3[/tex]
