Answer:
21
Step-by-step explanation:
Of means multiply and since we want an estimate we can round 72 to 70
30% * 70
.30 * 70

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
Answer:
4. false
5. false
Step-by-step explanation:
4. so sometimes it is false and sometimes true; i went with false just because sometimes it is not true and it not being true some of the time is definitely dominant.
5. simple. lol
Answer:84 degrees
Step-by-step explanation:
so if a triangle is 180 degrees in total you need to find how much you need to equal that so you add 59+37=96 degrees so then you will subtract 180-96=84 degrees
