Step-by-step explanation:
As per the question statement, a₁ is -6.25 and common ratio (r) is 1.25.
Therefore, the six terms of finite sequence would be as per the following equation . Thus, the series would be
- a1 = -6.25
- a2 = -6.25*r = -6.25*(1.25) = -7.8125
- a3 = -6.25*r^2 = -6.25*(1.25)^2 = -9.765625
- a4 = -6.25*r^3 = -6.25*(1.25)^3 = -12.20703125
- a5 = -6.25*r^4 = -6.25*(1.25)^4 = -15.2587890625
- a6 = -6.25*r^5 = -6.25*(1.25)^5 = -19.073486328125
So the points on the graph will be on following points,
(1, -6.25), (2, -7.8125), (3, -9.765625), (4, -12.20703125), (5, -15.2587890625), (6, -19.073486328125).
The graph would look like as attached.
Answer:
A)
Note that
Lower Bound = X - z(alpha/2) * s / sqrt(n)
Upper Bound = X + z(alpha/2) * s / sqrt(n)
where
alpha/2 = (1 - confidence level)/2 = 0.025
X = sample mean = 1723.4
z(alpha/2) = critical z for the confidence interval = 1.959963985
s = sample standard deviation = 89.55083319
n = sample size = 30
Thus,
Lower bound = 1691.355235
Upper bound = 1755.444765
Thus, the confidence interval is
( 1691.355235 , 1755.444765 ) [ANSWER]

b)
We assumed taht the distirbution of these observations is approximately normally distributed.

c)
Yes, because the values are not far away from each other.
7,000,000,000 + 0 + 50,000,000 + 1,000,000 + 0 + 0 + 4,000 + 200 + 60 + 4
I’m not sure if you’re supposed to put the commas in it
