Answer:
Odds for = Odds against = 1/2
Step-by-step explanation:
In a fair die, we have {1, 2, 3, 4, 5, 6} and
{1, 4, 5} and {2, 3, 6} constitute the entire sample space.
So, Probability of getting a 1 or a 4 or a 5
= Probability of getting a 1 +
Probability of getting a 4 +
Probability of getting a 5
=
=
Therefore, Odds for 1 or 4 or 5 = .
Since, Probability of getting a number between 1 and 6 is 1 and Probability of getting a number from 2 or 3 or 6 = , we have:
Probability of not getting a 1 or 4 or 5 = 1 -
=
Hence, odds for and odds against =
Answer:
Option D) There is sufficient evidence that the true population proportion is not equal to 70%.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 1165
p = 70% = 0.7
Alpha, α = 0.02
Number of people who agreed , x = 746
First, we design the null and the alternate hypothesis
This is a two-tailed test.
Formula:
Putting the values, we get,
Now,
Since,
Since, the calculated z statistic does not lie in the acceptance region, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.
Thus, there is enough evidence to support the claim that the true proportion differs from 70%.
Option D) There is sufficient evidence that the true population proportion is not equal to 70%.
