Answer:
Examine the given sequence. Which statement is not correct?
A) If c = 14, the relationship is linear and f(x) = 2x + 8 for x = {1, 2, 3, ...}.
B) If c = 14, the relationship is linear and an = 10 + 2(n − 1) for n = {1, 2, 3, ...}.
C) If c = 14.4, the relationship is exponential and f(x) = 10(1.2)(x − 1) for x = {1, 2, 3, ...}.
D) If c = 14.4, the relationship is exponential. a1 = 10 and an + 1 = an + 1.2 for n = {1, 2, 3, ...}.

Answer:
The answer is 4 whole 2 by 3 (4 2/3).
Step-by-step explanation:
(3/4) x = 3 1/2
3 x / 4 = 7/2
3 x = 14
x = 14/3 = 4 2/3.

Step-by-step explanation:
At 13% significance level, there isn't enough evidence to prove the administrators to claim that the mean score for the state's eighth graders on this exam is more than 280.
<h3>How to state hypothesis conclusion?</h3>
We are given;
Sample size; n = 78
population standard deviation σ = 37
Sample Mean; x' = 280
Population mean; μ = 287
The school administrator declares that mean score is more (bigger than) 280. Thus, the hypotheses is stated as;
Null hypothesis; H₀: μ > 280
Alternative hypothesis; Hₐ: μ < 280
This is a one tail test with significance level of α = 0.13
From online tables, the critical value at α = 0.13 is z(c) = -1.13
b) Formula for the test statistic is;
z = (x- μ)/(σ/√n)
z = ((280 - 287) *√78 )/37
z = -1.67
c) From online p-value from z-score calculator, we have;
P[ z > 280 ] = 0.048
d) The value for z = -1.67 is smaller than the critical value mentioned in problem statement z(c) = - 1.13 , the z(s) is in the rejection zone. Therefore we reject H₀
e) We conclude that at 13% significance level, there isn't enough evidence to prove the administrators to claim that the mean score for the state's eighth graders on this exam is more than 280.
