Astudy involves 669 randomly selected deaths, with 31 of them caused by accidents. construct a 98% confidence interval for the true percentage of all deaths that are caused by accidents.

Confidence Interval : 2.72% < p < 6.48%

Step-by-step explanation:

Number of randomly selected deaths = 669

Number of deaths caused by accident = 31

z-score for 98% confidence level = 2.326

Confidence Interval : 0.046 - 0.0188 < p < 0.046 + 0.0188

                                 : 0.0272 < p < 0.0648

                                 : 2.72% < p < 6.48%

Hence, Confidence Interval : 2.72% < p < 6.48%

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
