Answer:
store B, C, and D
Step-by-step explanation:
I hope this helps you
125-87,5=37,5
125 37,5
100 ?
?.125=100.37,5
?=3750/125
?=30
30%
Step-by-step explanation:
1=2 given
also 1=3. [ vertical opposite angles are equal]
From above equations:
2=3
corresponding angles are equal which means both lines are parallel.
Hope thus will help:)
Answer:
1. A matched-pairs t-test is valid, despite the sample being a small representation of the population, because the sample is a simple random sample and has a distribution with a single peak.
Step-by-step explanation:
The matched-pairs test is valid, for the reasons given in choice 1. Here's why:
- We do have matched pairs, not a 2-sample t-test, because each two are paired by the house they live in. Husband and wife live together: it's safe to pair them. (This rules out option 5.)
- Check conditions: The sample is large enough (fulfilling the <u>sample size condition)</u>. The sample data is fairly normal, although we don't know the population data, and the sample size is over 40, so we consider it a fairly large sample (fulfilling the <u>nearly normal condition)</u>. We don't know about outliers, but we'll have to assume Ted doesn't have any, because they aren't mentioned.
