Answer:
A.Because the confidence interval includes zero, the researcher can conclude the proportion of men and women who exercise regularly is the same.
Step-by-step explanation:
When the null value is contained in the confidence interval we tend to fail to reject the null hypothesis.
Here, the hypothesis according to scenario are
Null hypothesis: The Proportion of men and women who exercise regularly is same i.e. p1-p2=0.
Alternative hypothesis: The proportion of men and women who exercise regularly is not the same i.e. p1-p2≠0.
The null value here is 0. As the confidence interval is (-0.154,0.138) and it contains 0, so we fail to reject the null hypothesis and conclude that the proportion of men and women who exercise regularly is the same.

Answer: See below
Explanation:
1a.
-4 • 1 = 8(y-5)
-4 = 8y - 40
-8y = -40 + 4
-8y = -36
Y = -36/-8
Y = 9/2
1b.
3c - 6 = -6 + 9(c+9)
3c - 6 = -6 + 9c + 81
3c - 9c = 75 + 6
-6c = 81
C = 81/-6
C = 27/-2
2a.
6(p-2) = -2 + 3
6p - 12 = 1
6p = 13
P = 13/6
2b.
3x - 4 = -3 + 4(x - 3)
3x - 4 = -3 + 4x - 12
3x - 4x = -15 + 4
-x = -11
X = 11
Answer:
On logical Terms, Personal Director did not lie to you.
Step-by-step explanation:
For this question to be understood, you must take into account that how the phrase "only if" is used to relate sentences in formal logic.
Now you should remember that "P only if Q means" if P then Q.
Hence implying the same concept as mentioned above, here in this question, what the personal director really intended to convey was "If you are hired, then you have majored in mathematics or computer science, get a B average or better, and take accounting”.
Now we should remember that, this statement is not logically equivalent to "If you major in mathematics or computer science, get a B average or better and take accounting, then you will be hired".
Hence on logical grouds, Personal director did not lie to you. You were not attentive enough to sort out the turgid strategy he utilized.
