Given:
n = 20, sample size
xbar = 17.5, sample mean
s = 3.8, sample standard deiation
99% confidence interval

The degrees of freedom is 
df = n-1 = 19

We do not know the population standard deviation, so we should determine t* that corresponds to df = 19.
From a one-tailed distribution, 99% CI means using a p-value of 0.005.
Obtain
t* = 2.8609.

The 99% confidence interval is
xbar +/- t*(s/√n)

t*(s/√n) = 2.8609*(3.8/√20) = 2.4309
The 99% confidence interval is
(17.5 - 2.4309, 17.5 + 2.4309) = (15.069, 19.931)

Answer: The 99% confidence interval is (15.07, 19.93)

S = vt + 16t^2, solve for v.
Phoenix [80]
S=vt+16t^2\ \ \ \ \ | subtract\ 16t^2\\\\
S-16t^2=vt\ \ \ \ \ | divide\ by\ t\\\\
\frac{S-16t^2}{t}=v\\\\\Solution\ is\ v=\frac{S-16t^2}{t}.
