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
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
no correlation because as the number of people who biys tickets it doesn affect the value of the grand prize since it is chosen before the amount of tickets are sold
3. 15 + 4 =19 altogether 15+19= 34
4. 10 × 5 =50 $ are made from children

Hello! answer: 7
Step-by-step explanation:
80 + 80 = 160 360 - 160 = 200 200 ÷ 2 = 100 and 14 × 7 = 98 and 98 + 2 = 100 therefore x = 7 HOPE THAT HELPS!
