Suppose that 100 people who recently bought houses are surveyed, and the monthly mortgage payment and gross income of each buyer are determined. Let y denote the mortgage payment and x the gross income. Suppose that x? = $3100 y? = $868 s_x = $1200 s_y = $250 ?? = 0.85 n = 100 a Estimate the ratio of the mortgage payment to the gross income and place a bound on the error of estimation. b Find a 95% confidence interval for the ratio of the mortgage payment to the gross income.

Step 1
We are given the following information: - \(x = \$3100\) is the mean mortgage payment. - \(y = \$868\) is the mean gross income. - \(S_x = \$1200\) is the standard deviation of the mortgage payments. - \(S_y = \$250\) is the standard deviation of the gross Show more…

Calculate the $95 \%$ confidence interval for the difference in population proportions for each of the following: a. $\begin{aligned} n_{x}=350 & \hat{p}_{x}=0.64 \\ n_{y}-300 & \hat{p}_{y}-0.68 \end{aligned}$ b. $\begin{aligned} n_{x}=245 & \hat{p}_{x}=0.45 \\ n_{y}=230 & \hat{p}_{y}=0.48 \end{aligned}$
Assume simple random sampling. Calculate the $95 \%$ confidence interval estimate for the population mean for each of the following. a. $N=1200 ; n=80 ; s=10 ; \bar{x}=142$ b. $N=1425 ; n=90 ; s^{2}=64 ; \bar{x}=232.4$ c. $N=3200 ; n=200 ; s^{2}=129 ; \bar{x}=59.3$
Calculate the confidence interval to estimate the population proportion for each of the following. a. $98 \%$ confidence level; $n=450 ; \hat{p}=0.10$ b. $95 \%$ confidence level; $n=240 ; \hat{p}=0.01$. c. $\alpha=0.04 ; n=265 ; \hat{p}=0.50$
