Answer:
We don´t have at 95% of confidence, evidence to reject the publisher´s claim
Step-by-step explanation:
Population mean p₀ = 58 % or p₀ = 0,58
Hypothesis Test:
Null Hypothesis H₀ p = p₀
Alternative Hypothesis Hₐ p < p₀
For a significance level α = 0,05 means that CI = 95 % or CI = 0,95
z(c) = - 1,64
MOE = z(c)* √(p*q)/n
p - p₀ / √(p*q)/n = z(s)
And that z(s) is in the acceptance region
|z(s)| < |z(c)|
|z(s)| < 1,64
Then if that so we fail to reject H₀ . We don´t have evidence to reject the publisher´s claim
C and D are correct as you move the decimal however many zeros are on the end of the multiplier. For instance, 10 equals one decimal change as it only has one zero. 100 has two and 1000 has three, etc.
X4 + 8 = -36
x4 = -44
x = -11
(-11)4 + 8 = -36
-44 + 8 = -36
-36 = -36
