Answer:
|x| + |y| = 29
Step-by-step explanation:
We have been given the expression;
|x| + |y|
We are required to evaluate the above expression if;
x = 16 and y = 13
The parallel vertical lines imply that we are dealing with the absolute value of x and y;
|x| + |y| = |16| + |13|
= 16 + 13
= 29

Answer:
H0 : μ2004 - μ2000 = 0
Step-by-step explanation:
Given the data:
Year ________: 2000 ___ 2004
Mean ________ 27.34 ___ 48.12
Std. Dev _______10.11 ____ 19.23
Unweighted n 43 54
The hypothesis is to test if there was a significant difference in the average number of hours worked in a week from 2000 to 2004 ;
Hence, the null hypothesis will negate the hypothesis, that is there is no difference in the average hours worked in a week from 2000 to 2004
Null hypothesis ; H0 : μ2 - μ1 = 0
Alternative hypothesis ; H1 : μ2 - μ1 ≠ 0
