<h2>Answer with explanation:</h2>
The confidence interval for population mean is given by :-
Given : Sample size : n=106
Sample mean :
Standard deviation :
Significance level :
Critical value :
Then , 99% confidence interval estimate of the mean body temperature of all healthy humans will be :-
Since 98.6 is higher than the upper limit of the confidence interval (98.473), then this suggest that the mean body temperature could be lower then 98.6 degrees.
The best estimate of population mean is always the sample mean.
Answer:
Workers of army contract were more productive.
Step-by-step explanation:
To determine on which contract the workers were more productive compute the work done per hour by the workers for both contracts.
- <u>Navy Contract</u>:
Number of devices = 2,300
Number of workers = 25
Number of weeks = 2 weeks
Number of hours per week = 40
The number of hours it took 25 workers to produce 2300 devices is =
Then number of devices produced in 1 hour is =
- <u>Army Contract</u>:
Number of devices = 5,500
Number of workers = 35
Number of weeks = 3 weeks
Number of hours per week = 40
The number of hours it took 35 workers to produce 5500 devices is =
Then number of devices produced in 1 hour is =
The workers for the army contract are more productive since they produce 1.31 devices per hour whereas the workers for navy contract produces 1.15 devices per hour.
