PSYCHO15rus [73]

Answer:

(513.14, 860.36) is a 98% confidence interval for the true mean

Step-by-step explanation:

We have a small sample size of n = 15, the mean balance was \bar{x} = 686.75 with a standard deviation of s = 256.20. The confidence interval is given by \bar{x}\pm t_{\alpha/2}(\frac{s}{\sqrt{n}}) where t_{\alpha/2} is the 100(\alpha/2)th quantile of the t distribution with n-1=15-1=14 degrees of freedom. As we want a 100(1-\alpha)% = 98% confidence interval, we have that \alpha = 0.02 and the confidence interval is 686.75\pm t_{0.01}(\frac{256.20}{\sqrt{15}}) where t_{0.01} is the 1st quantile of the t distribution with 14 df, i.e., t_{0.01} = -2.6245. Then, we have 686.75\pm (-2.6245)(\frac{256.20}{\sqrt{15}}) and the 98% confidence interval is given by (513.1379, 860.3621)

Geometry

A point P on the line segment GK may be parametrically represented as

P = (1-t)G + tK

t is a real parameter which controls where on the segment P is.  t=0 means P=G, t=1 means P=K.  We're interested in the t that gives a 3:2 ratio for PG:PK.  That's closer to K so t>1/2.   t=3/(3+2) = 3/5.

P=(1-3/5)(1,2) + (3/5)(8,12) = (2/5,4/5)+(24/5,36/5)=(26/5,40/5)=(26/5,8)

Answer: (26/5, 8)
