Answer:
a) The confidence interval is 
.
Step-by-step explanation:
We have to calculate a confidence interval (CI) of a difference of proportions.
For the existing procedure, the proportion is:
For the new procedure, the proportion is:
To calculate the CI, we need to estimate the standard deviation
For a 90% CI, the z-value is 1.64.
Then, the CI is:
Answer:
<h2>70 ft</h2>
Step-by-step explanation:
120 below we can use a model to figure this out.
sea level is 0
the submarine <u>goes 120 down</u>, so its -120
it <u>goes up by 50</u>, so now its <em>70</em>
no other obstacles, 70 or A is your answer.
Let us say that t is number of months and n is the number
of cases of Bangkok flu, therefore the equation we can create here is:
dn / dt = 10 t + 450
<span>where 10 represents the slope and 450 represents the
y-intercept</span>
It is answer #1.
m + g must be less than or = 40 hours
12m + 14g must be greater than or = $250
I think this is the answer to your question And also the solution
