Let us say, the numbers are "a" and "b"
so their sum is 336, or
a + b = 336
and the first one is bigger than the second by 124
so... whatever "b" is, "a" is THAT plus 124, or
a = b + 124
thus one can say
a + b = 336
or
(b + 124) +b = 33
solve for "b"
what is "a"? well, a = b + 124
We have to find converse of the given statement "If his shoes are clean, then he did not walk in the mud."
Before that we need to know what is called converse.
Say if given statement is " If P then Q" then it's converse is given by "If Q then P".
So basically we just need to sqitch the two parts of statements as given in definition.
Hence final answer will be "If he did not walk in the mud then his shoes are clean."
Answer:
b) B and D and c) A and C
Step-by-step explanation:
The hypotheses would be:
(Right tailed test at 5% level)
Sample proportions are
Sample A B C D
Success 31 34 27 38
Proportion p 0.775 0.85 0.675 0.95
Std error
(sqrtpq/n) 0.066 0.056 0.074 0.034
p diff
p-0.75 0.025 0.10 - 0.075 0.20
Z stat
p diff/SE 0.0757 1.77 1.01 5.80
p value 0.469 0.038 0.156 0.000001
we find that p value is more smaller than alpha, the more accurate the alternate hypothesis.
b) Only B and D provide against the null. Because p <0.05
c) A and C provide no evidence for the alternative because p >0.05
