Answer:
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where = Population standard deviation.
n= sample size
= Sample mean
z* = Critical z-value .
Given :
n= 49
Two-tailed critical value for 95% confidence interval =
Then, the 95% confidence interval would be :-
Hence, the 95% confidence interval for estimating the population mean :
Answer: D. The length is 13 units.
Step-by-step explanation:
(-1, -3 ) Find the difference between the x values and y values.
(11, -8)
-3-(-8) = 5
-1-11 = -12 now find the absolute values.
The absolute value of 5 is 5 . The absolute value of -12 is 12.
Now use the Pythagorean Theorem formula a^2 + b^2 =c^2 where c square is the length between AB.
5^2 + 13^2 = C^2
25 + 144 = c^2
169=c^2
c= 13
