Answer: where is the picture show it to me so that there’s none
Step-by-step explanation:
Answer: 315,392
Step-by-step explanation: this took me some time but I multiplied multiple times each time and I got this I hope it’s correct.
Btw I multiplied 2 times 8 then multipled with 11 then multipied 172 times 8 then multiplied by 14 and got 19,712. Then, I multiplied 19,712 by 16 and got 315,392
I had to edit cause I miscalculated :/ anyways I hope this is correct
Answer:
<h2>Time is the independent variable and Height of the Grass is the dependent variable.</h2>
Step-by-step explanation:
The graph is about the height of the grass thourgh time, that means Brady is analysing how long it takes to the grass to grow.
It's important to know that time is a variable which doesn't depends on any other variabel, that is, it's an independent variable all the time.
Therefore, Time is the independent variable and Height of the Grass is the dependent variable.
This is just simple deduction, because the grass grows through time, it doesn't happen in the opposite way, time doesn't change accoring to the height of the grass.
Using the margin of error for the z-distribution, the sample sizes are given as follows:
a) 822.
b) 1068.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

The margin of error is given by:

In which:
is the sample proportion.
We have a 95% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
Item a:
The estimate is of
, hence we solve for n when M = 0.03.





n = 821.2
A sample of 822 is needed.
Item b:
No prior estimate, hence
.





n = 1067.11
A sample of 1068 is needed.
