here x = option c and here y= option a
Answer:
The sampling distribution of X is exactly binomial with n = 1200 and p = 0.25
Step-by-step explanation:
For each person surveyed, there are only two possible outcomes. Eithey they support his proposition, or they do not support his proposition. So the sampling distribution of X is exactly binomial.
Binomial probability:
Probability of exactly x sucesses on n repeated trials, with a p probability.
He surveyes 1200 likely voters, so ![n = 1200](https://tex.z-dn.net/?f=n%20%3D%201200)
He believes he could gain the support of 25% of likely voters. So
.
The correct answer is:
The sampling distribution of X is exactly binomial with n = 1200 and p = 0.25

Step-by-step explanation:
Simplify
6.6-3.2 +
=
First, Subtract <u>(6.6 - 3.2)</u>
<u>= 3.4</u>
<u>Then with the fraction</u><u>, add the result of the subtaction by the fraction:</u>
= 3.4 +
, using happy face method
Multiply denominators (1×10) and multiply in X (3.4×10) + (1×1)
=
+

= ![\frac{1\cdot \:1}{7\cdot \:10}](https://tex.z-dn.net/?f=%5Cfrac%7B1%5Ccdot%20%5C%3A1%7D%7B7%5Ccdot%20%5C%3A10%7D)
Answer: ![\frac{1}{70}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B70%7D)
B. ![\frac{7}{3}\div \:10](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B3%7D%5Cdiv%20%5C%3A10)
= ![\frac{7}{3}\cdot \frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B3%7D%5Ccdot%20%5Cfrac%7B1%7D%7B10%7D)
Answer: ![\frac{7}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B30%7D)
C. - 7/10
= - 0.7 (NEGATIVE SIGN)
D. 7/10
= 0.7 ( POSITIVE SIGN)
