Since annual means per year, then you need to divide 22 by 5.
5 / 22 = 4.4
Now lets check our work.
4.4 x 5 = 22
Answer:
With 95% confidence when n equals 44, the population mean is between a lower limit of 33.96 and an upper limit of 40.04
Step-by-step explanation:
Confidence Interval = mean + or - Error margin (E)
mean = 37
sd = 10
n = 44
degree of freedom = n - 1 = 44 - 1 = 43
t-value corresponding to 43 degrees of freedom and 95% confidence level is 2.0165
E = t × sd/√n = 2.0165×10/√44 = 3.04
Lower limit = mean - E = 37 - 3.04 = 33.96
Upper limit = mean + E = 37 + 3.04 = 40.04
95% confidence interval is between 33.96 and 40.04

Answer:
315
Step-by-step explanation:
because 15% of 2,100 is 315
Tan 40 = h / 20 where h = height of the pole.
h = 20 tan 40 = 16.78 feet
