The solution would be like this for this specific problem:
H0: p = p0, or <span>
H0: p ≥ p0, or
H0: p ≤ p0 </span>
find the test statistic z
= (pHat - p0) / sqrt(p0 * (1-p0) / n)
where pHat = X / n
The p-value of the test is
the area under the normal curve that is in agreement with the alternate
hypothesis. <span>
H1: p ≠ p0; p-value is the area in the tails greater than |z|
H1: p < p0; p-value is the area to the left of z
H1: p > p0; p-value is the area to the right of z </span>
Hypothesis equation:
H0: p ≥ 0.67 vs. H1: p
< 0.67
The test statistic is: <span>
z = ( 0.5526316 - 0.67 ) / ( √ ( 0.67 * (1 - 0.67 ) / 38 )
z = -1.538681 </span>
The p-value = P( Z < z
) <span>
= P( Z < -1.538681 )
<span>= 0.0619</span></span>
Answer:
D
Step-by-step explanation:
2000=1 ton so 4000=2tons
3/4 of 540 is 540×0.75=405 miles
405÷45=9 hours
It will take Tameron 9 hours to drive to his college.
Answer:
The answer to your question is:
a) as a decimal number = 0.00055
b) as a percent 0.055%
Step-by-step explanation:
Data
Navajo people = 169 000
American people = 308 700 000
a) Navajo people as a decimal number = 169 000 / 308 700 000
= 169 / 308 700
= 0. 00055
b) 308 700 000 -------------------- 100 %
169 000 --------------------- x
x = 169000(100) / 308700000 = 0.055
Answer:
x = 15 cm
Step-by-step explanation:
Use Pythagorean thm:
9² + 12² = x²
81 + 144 = x²
225 = x²
√225 = √x²
15 = x
