Answer:
We fail to reject the null hypothesis at 0.05 significance level. We cannot say that less than 12% of trips include a theme park visit.
Step-by-step explanation:
let p be the proportion of trips included a visit to a theme park.
: p=0.12
: p<0.12
To test, we need to calculate test statistic of the sample proportion as:
z=
where
- p(s) is the sample proportion of trips included visit to a theme park (
- p is the proportion assumed under null hypothesis. (0.12)
- N is the sample size (1565)
Using the numbers, z=
= −0.767 and p(z) is ≈0.222
Since 0.222 > 0.05 we fail to reject the null hypothesis.
Answer:
y-5=-6/5(x+2)
Step-by-step explanation:
m=(5+1)/(-2-3)
m=6/-5
Answer:
10.875 total, 1.5 times each are below.
Step-by-step explanation:
1.5 (1 1/2) x 1.5 = 2.25
0.5 (2/4) x 1.5 = 0.75
0.125 (1/8) x 1.5 = 1.875
4 x 1.5 = 6
2.25 + 0.75 + 1.875 + 6 = 10.875 total
Answer:
We know that, i = √-1 => i² = -1
- <u>143 - 24i</u> is the right answer.
Answer:
5/24
Step-by-step explanation:
If we want to know the value between 1/4 and 1/6, we have to add both values and divide them by 2.
1/4 1/6
o add the values they have to have the same denominator
A simple way to find one in common is to multiply both denominators with each other.
6 * 4 = 24
now we calculate the equivalent fractions for that denominator
1/4 * 6/6 = 6 / 24
1/6 * 4/4 = 4 / 24
finally we add and divide by 2 and get the value
(4/24 + 6/24) / 2 =
(10/24) / 2 =
5/24
as we can see the value is different from 1/5
