The management of a water park has concerns about the chlorine level of 0.4% mg/mL increasing to an unsafe level.The management tests the hypothesis that the park's chlorine proportions have remained the same.An independent agency ran a test on a random sample size of 100001000010000 and found the chlorine level at 0.5% mg/mL.Create a 95% confidence interval for the proportion of chlorine in the water.
A) Based on the data,we are 95% confident the proportion of chlorine in the water is between 0.102% and 0.898%.
B) Based on the data,we are 95% confident the proportion of chlorine in the water is between 0.109% and 0.891%.
C) Based on the data,we are 95% confident the proportion of chlorine in the water is between 0.362% and 0.638%.
D) Based on the data,we are 95% confident the proportion of chlorine in the water is between 0.009% and 0.891%.
E) Based on the data,we are 95% confident the proportion of chlorine in the water is between 0.4% and 0.6%.
Chlorine Level
The concentration of chlorine present in a substance, commonly measured in water to ensure safety and hygiene.
Confidence Interval
A range of values derived from sample data that is likely to contain the true population parameter with a specified level of confidence.
Water Park
A recreational facility featuring water play areas, such as swimming pools, water slides, and splash pads.
