question 49

Short Answer

Instruction 10-8
The following Micosoft Excel output contains the results of a test to determine if the proportions of satisfied guests at two resorts are the same or different.
$$\begin{array}{l}\begin{array} {| l | l |} \hline \text {Hypothesised Difference }&0\\\hline \text {Level of Significance }&0.05\\\hline \text {Group 1 }&\\\hline \text {Number of Successes }&160\\\hline \text { Sample size}&200\\\hline \text {Group 2 }&\\\hline \text {Number of Successes }&172\\\hline \text {Sample Size }&250\\\hline \text {Intermediate Calculations }&\\\hline \text {Group 1 Proportion }&0.8\\\hline \text {Group 2 Proportion }&0.688\\\hline \text { Difference in Two Proportions}&0.112\\\hline \text {Average Proportion }&0.737777778 \\\hline \text { Test Statistic}&2.684103363 \\\hline \text {Two-Tailed Test }&\\\hline \text { Lower Critical Value}&-1.95996398 \\\hline \text {Upper Critical Valuse }&1.959963985 \\\hline \text {p-Value }&0.007272462\\\hline \end{array}\end{array}$$
-Referring to Instruction 10-8,construct a 90% confidence interval estimate of the difference in the population proportion of satisfied guests between the two resorts.
