Step-by-step explanation
The answers in bold is what was required from the question.
the null hypothesis using symbol:-
H₀ : μ = 11.80
the alternative hypothesis using symbol:-
H₁: μ ≠ 11.80
This is a one tailed test. Given what you know, you will evaluate this hypothesis using a t test statistic.
Alpha level = 0.05
Sample size = n
Degree of freedom = n-1 = 40-1 = 39
To use the t distribution we will have to find the critical value from the t table this value is 1.685
But the question does not have sample mean and sample standard deviation. So I was unable to solve for the standard error
Answer:
The correct answers are as follows.
a. 8.624%
b. 60.84%
c. 27.75%
Step-by-step explanation:
In order to find each of these, take the likelihood of each of steps and multiply them together.
a. For this one, we need to note that the first two spins should not be blue. The likelihood of them not being blue is the chance for red and green put together (37%). Then we want the third spin to be the blue odds (63%)
.37 * .37 * .63 = .08624 = 8.624%
b. For the purpose of this, we are looking just for the first two spins to not be red (78% probability). After that, it does not matter what the third spin is since it says "at least 3 times)
.78 * .78 = .6084 = 60.84%
c. For this one, we need to combine two things. Firstly, the chance that the first spin is green (15%). Then we would add in the likelihood that the first spin is not green (85%), but the second is.
.15 + (.85 * .15) = .2775 = 27.75%

Answer:
∠x = 92°
Step-by-step explanation:
Supplementary means that the angles add up to 180°. Since one of them equals 88°, the other one or ∠x equals:
![180-88 = 92](https://tex.z-dn.net/?f=180-88%20%3D%2092)
So, ∠x = 92°
whatttttttt? i have no idea what that is
