Answer:1. 20
2.27
Step-by-step explanation:
1. 20* 3 = 60
2.27* 3 = 81
For the first one is definitely 0.12
The second one I was having trouble with, but I know it is not .25 or .75. Looking at the leftover answers I would say .36 because I already used .12. Also .52 and .25 are the givens.
Answer:
16,000
Step-by-step explanation:
to round to the nearest thousand you must look at the thousands place and then look to the number next to it
if the number is 0 1 2 3 or 4 the thousands place stays the same
if the number is 5 6 7 8 or 9 the thousands place goes up one
in this case it is 0
so it stays the same
16,000 is your answer
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.
