Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population mean when the population standard deviation is not known is:
The information provided is:
Compute the 90% confidence interval for population mean length of eastern rods as follows:
Thus, the 90% confidence interval for population mean length of eastern rods is (23.73, 24.07).
The correct answer is A. When dealing with an absolute value inequality, you want to flip the positive to a negative sign, as well as flip the inequality sign.
80 is 80% of 100; 80/100=0.80=80% c:
Answer:
157.5 square feet
Step-by-step explanation:
If an inch is 3 feet, then
3.5 inches = 10.5 feet (3.5*3)
5 inches = 15 feet (5*3)
The area of a rectangle is length times width so...
10.5*15 = 157.5
Step-by-step explanation:
3 29/31 + 9 13/14 * 26 6/7 =0
first 26 6/7 = 26 13/14
3 29/31 +( 26 13/14 * 9 13/14)
3 29/31 + 266 32/49
Answer :
270 894/1519 / 270.5585 / 411024/1519
