2p-4+16=5p-9
-3p-4+16=-9
-3p-4=16+-9
And if you can solve from there cuz that's a lot of mental math for me. if u see these:() always distribute whatever is before it. I can check your answer when you are finished tho
Answer with explanation:
Let p be the population proportion.
Given : The chain will open if there is evidence that more than 5,000 of the 20,000 households in the area are equipped with Blu-ray players.
i.e.
Since alternative hypothesis is right-tailed , so the test is right-tailed test.
Also, Sample size : n= 300 ,
Sample proportion:
Test statistic:
i.e. Observed test statistic Value = 2.80
(A) is right option.
Critical value for 5% significance level for right tailed test :-
Since , the observed z-value is greater than the critical value , so we reject the null hypothesis.
Conclusion : We have sufficient evidence to supposrt the alternative hypothesis.
So, The chain will open if there is evidence that more than 5,000 of the 20,000 households in the area are equipped with Blu-ray players.

Answer:
12.77%
Step-by-step explanation:
if a 100% is 9.4
then do
8.2/9.4
which is
0.87234042553
which is
87.23%
then do
100% - 87.23%
which is
12.77%
Answer:
10
Step-by-step explanation:
number of slices = 6 slices
amount each student receives = 3/5 slice per student
number of students
= number of slices / number of slices per student
= 6 ÷ (3/5)
= 6 x (5/3)
= 30/3
= 10 students
