Thus, the null and the alternative hypothesis can be computed as:
Null hypothesis:
Alternative hypothesis:
Answer:
y = 24
Step-by-step explanation:
8 : 4 : : y : 48
8 / 4 = y / 48
1 / 2 = y / 48
y = 48 / 2
y = 24
The quotient of -3/8 and -1/3 is 1 1/8.
2009 - 1894 = 115
That appears to be the same number as
the one that appears in Choice-'B'.
If order doesn't matter (e.g. all the positions in the committee are essentially identical) then the number of possible choices is
.
