Answer:
Step-by-step explanation:
We need to evaluate if thickness of a 10 gauge metal sheet is a requiered in the process that means 3.416 mm thick. So that should be our null hypothesis; μ₀ = 3.416 and based on sample data, we will formulate an alternative hypothesis taking into account the mean, and standard deviation obtained. We surely will have better information to take a decision
A
you have to solve x^2+x-5=0
So x=(-1 +/- sqrt(1^2+4*1*5))/2
x=(-1 +/- sqrt(21))/2
2.96 meters per second is the answer I'm getting. I took the total seconds and divided it by how many times he ran around the track to get his speed for lap and then I divided his lap speed by how long the track was to get his meters per second
Answer: parameter: The proportion of registered voters who will vote Yes on the measure.
Sample: The 1000 registered voters who participated in the study.
Statistic: The proportion of the 1000 registered voters that were surveyed who will vote Yes on the measure.
Variable: Yes or No for each registered voter
Population: All registered voters in the US
Data: The list of Yes and No answers that were given by the 1000 participants in the study.
Step-by-step explanation:
Definitions of the given terms:
- Population: Large groups of individuals having similar characteristics as per the researcher's point of view.
- Sample: It is a subset of the population used to represent it.
- Parameter: Measure of particular characteristics in the population.
- Statistic: Measure of particular characteristics in the sample.
- Variable: Characteristics that vary.
- Data: A collected information facts and statistics.
Hence, by using the above definitions, we have
- Parameter: The proportion of registered voters who will vote Yes on the measure.
- Sample: The 1000 registered voters who participated in the study.
- Statistic: The proportion of the 1000 registered voters that were surveyed who will vote Yes on the measure.
- Variable: Yes or No for each registered voter.
- Population: All registered voters in the US.
- Data: The list of Yes and No answers that were given by the 1000 participants in the study.
