A random sample of 12 families were asked how many kids they had. The data are given below. According to the US Census, families have on average 2.4 kids per family. What is the p-value for the alternative hypothesis that the average number of kids per family is different than the US Census value?
1 1 2 2 2 3 3 3 3 4 4 6
A) p-value = 1.070.
B) p-value = 0.154.
C) p-value = 0.846.
D) p-value = 0.308.
Answer:
0.308
Step-by-step explanation:
Given the data:
1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 6
We need to obtain the sample mean and sample standard deviation :
Sample mean, xbar = Σx/n
Where n = sample size (1+1+2+2+2+3+3+3+3+4+4+6) / 12 = 2.833
Sample standard deviation, s
Using the formula :
s = √Σ((x - xbar)² / n-1)
s = 1.40
Hypothesis :
H0 : μ = 2.4
H1 : μ ≠ 2.4
The test statistic :
(xbar - μ) ÷ (s/√(n))
(2.833 - 2.40) / (1.40/sqrt(12))
Test statistic = 1.0713
Using the Pvalue from Test score calculator :
df = n - 1 = 12 - 1 = 11 ; two tailed
Pvalue(1.071, 11)
= 0.3069
= 0.307

Find the approximate circumference of a circle with a diameter of 100 yards.
O 628 yards
31 yards
157 yards
314 yards
Answer:
D. 314 yds
Step-by-step explanation:
Given:
Diameter = 100 yds
Required;
Circumference of the circle
Solution:
Circumference of circle = πd
Plug in the value
Circumference = π × 100
= 314 yds (nearest whole number)

Determine the ratio of the notes to middle C.
Express the answers as a simple integer ratio. (Ratios will be approximate due to rounding.)
The smaller the numbers in the ratio, the greater the consonance. Decide which of the notes when played with middle C would have the greatest dissonance.
a. G and C
b. B and C
c. D and C
d. E and C
Please select the best answer from the choices provided
Answer:
B. B and C
Step-by-step explanation:
I calculated it logically
Answer:
The answer would be a. G and C.
Step-by-step explanation:
When calculating G/C, 329/261.6= 1.49847 rounded.
We are looking for the closest integer ratio to that number which is 3 to 2. A 3/2 ratio =1.5 which is as close to 1.49847 as you are going to get with a ratio. Hope this helps!

14. Which of the following ratios is not equal
to the ratio 12:36?
(1) 3:9
(2) 5:15
(3) 9:36
(4) 10:30
(5) 16:48
12:36 = 1:3,
3:9 = 1:3
5:15 = 1:3
9:36 = 1:4
10:30 = 1:3
16:48 = 1:3
So, 9:36 is the answer.

Please help me solve this problem
Answer:
D, 225
Step-by-step explanation:
Because this equation already has a1, it's useless to test with that, so instead solve for a2.
You would have a2 - 5a1, which would get you a2 = 5(9) because we already know what a1 is, which is 9. a2 = 45
Now we have a2, which is 45, so now we solve for a3
We would have a3 = 5a2 = a3 = 5(45) which is 225 which is a3
