1-2. The best estimate for the population mean would be sample mean of 60 gallons. Since we know that the sample mean is the best point of estimate. Since sample size n=16 is less than 25, we use the t distribution. Assume population from normal distribution.
3. Given a=0.1, the t (0.05, df = n – 1 = 15)=1.75
4. xbar ± t*s/vn = 60 ± 1.75*20/4 = ( 51.25, 68.75)
5. Since the interval include 63, it is reasonable.

Answer:
Step-by-step explanation:
let workers=n
time=t(weeks)
t=k/n ,where k is constant .
when t=8,n=3
8=k/3
k=24
t=24/n
n 2 4 6 12
t 12 6 4 2
