Question 22 points Save Answer
Suppose that in an industrial town with many factories. 135 cases of respiratory infection were diagnosed in January and 173 cases were diagnosed in February. A total of 3,500 people live in the
town. What is the appropriate interpretation of the attack rate of respiratory infections over the two months?
For every 1,000 residents. 880 were treated for a respiratory infection
The prevalence of respiratory infections in the town during January February was 8.8%
Nearly 90 of every 1,000 respiratory infections can be attributed to work in the factories
Almost nine percent of the town's residents developed a respiratory infection during the months of January and February

Answer:

Confidence levels are expressed as a percentage (for example, a 95% confidence level). It means that should you repeat an experiment or survey over and over again, 95 percent of the time your results will match the results you get from a population (in other words, your statistics would be sound!). Confidence intervals are your results…usually numbers. For example, you survey a group of pet owners to see how many cans of dog food they purchase a year. You test your statistics at the 99 percent confidence level and get a confidence interval of (200,300). That means you think they buy between 200 and 300 cans a year. You’re super confident (99% is a very high level!) that your results are sound, statistically.

Confidence Interval For a Sample: Steps

Question:

A group of 10 foot surgery patients had a mean weight of 240 pounds. The sample standard deviation was 25 pounds. Find a confidence interval for a sample for the true mean weight of all foot surgery patients. Find a 95% CI.

Step 1: Subtract 1 from your sample size. 10 – 1 = 9. This gives you degrees of freedom, which you’ll need in step 3.

Step 2: Subtract the confidence level from 1, then divide by two.

(1 – .95) / 2 = .025

Step 3: Look up your answers to step 1 and 2 in the t-distribution table. For 9 degrees of freedom (df) and α = 0.025, my result is 2.262.

Step 4: Divide your sample standard deviation by the square root of your sample size.

25 / √(10) = 7.90569415

Step 5: Multiply step 3 by step 4.

2.262 × 7.90569415 = 17.8826802

Step 6: For the lower end of the range, subtract step 5 from the sample mean.

240 – 17.8826802 = 222.117

Step 7: For the upper end of the range, add step 5 to the sample mean.

240 + 17.8826802 = 257.883

That’s how to find the confidence interval for a sample, hope that helped!

Answer:

7/3 mi

Explanation:

1+3/4=7/4

3/4=1 so 1:3/4 as x:7/4

= then cross multiply

(3/4)x=7/4

x=7/4(4/3)

x=7/3

Training workers to recognize and avoid unsafe conditions

Explanation A hazard is anything that has potential to cause harm either an incident or or an accident. OSHA which is a an occupational safety and healthy agency requires that  employers and workers to come up with the information concerning the hazards which are in a work place or the potential ones that may occur during the working period. This is done by conducting inspections on the work place. And Train the workers to recognize and avoid unsafe conditions during the working period.
