Answer:
We do not reject the Null Hypothesis
Step-by-step explanation:
From the question we are told that:
Sample size 
Population mean 
Sample mean 
Standard deviation 
Significance level 
Generally the Null and and alternative Hypothesis are as follows


Therefore t critical Value is


Where

Therefore
From t Table

Generally the equation for Z Critical is mathematically given by



Therefore
Since the t test statistics is greater than the Critical value
Hence,we do not reject the Null Hypothesis
Answer:
B) 2
Step-by-step explanation:
The first differences are increasing by 1 from term to term:
8-12 = -4
5-8 = -3
3-5 = -2
2-3 = -1 . . . . . if the next term is 2, as we believe it should be.

<em>Comment on number sequences</em>
Any finite length sequence of n numbers can be modeled exactly by an n-1 degree polynomial. That is, a 4th-degree polynomial can be made to describe the sequence regardless of the next term you may choose.
If you choose the next term to be 2 as we suggest, then the sequence can be modeled by a 2nd-degree polynomial ...
(n² -11n +34)/2 . . . . for n = 1, 2, 3, ...
Answer:
x^(6/35)
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)^c = a^(bc)
