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)

dogs + cats = 11x

hence x=11

dogs = 6x = 6×11 = 66
