Construct an 95% confidence interval for the population proportion of successes. (Round intermediate calculations to 4 decimal places, \"z\" value to 2 decimal places, and final answers to 3 decimal places.)
Construct an 95% confidence interval for the population proportion of failures. (Round intermediate calculations to 4 decimal places, \"z\" value to 2 decimal places, and final answers to 3 decimal places.)
| A random sample of 10 observations results in 6 successes. Use Table 1. |
Solution
proportion of success = 6/10 =0.6;
standard error = 0.1549
95% confidence interval for the population proportion of success is (0.2964,0.9036)
proportion of failures = 4/10 =0.4
95% confidence interval for the population proportion of faulutres is (0.0964,0.7036)
