Step-by-step explanation:
I just took the test on Edgenuity 2020. Good luck
For finding y-intercept we equalise x by zero
y = 3x+17
y =3(0)+17
y = 0+17
y = 17
y-intercept : (0,17)

Plug in 2 for t.
=> -16*(2^2) +80*2 +3
=> -16*4 +160 +3
=> -64+163
=> 99
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:
