Is the null hypothesis rejected or not rejected for an observed p-value of at 0.07 at a significance level of 0.05? Group of ans
1 answer:
Answer: B) Do not reject null hypothesis
Step-by-step explanation:
When p-value is less than the significance level then we reject the null hypothesis .
When p-value is greater than or equal to the significance level then we fail to reject the null hypothesis.
Given : P-value = 0.07
Significance level = 0.05
Clearly , 0.07> 0.05
i.e. P-value > Significance level
⇒ We fail to reject the null hypothesis.
Hence, the correct answer is : B) Do not reject null hypothesis

The problem given is:
_______________________________
Evaluate: log 2 base 8 .
_______________________________
Rewrite as: " " ;
_______________________
Take note of the following definition of a logarithm:
_______________________
" " ; ↔ "
" ;
_______________________
in which: refers to the "base" ;
refers to the "argument" ;
refers to the "exponent" ;
______________________________
As such:
" "
⇔ " " ; Solve for "x" ;
_______________
Note:
2⁰ = 1 ;
2¹ = 2 ;
2² = 2 * 2 = 4 ;
2³ = 2 * 2 * 2 = 8 .
___________________
→ " " ;
→ " " ; since: "
" ;
→ as such: " x = 3 " ;
______________________
Thus:
"log 2 base 8 " ;
= .
