Answer:
r symbolizes a value of the linear correlation coefficient calculated for from the specific paired sample data in the sample .
ρ is a Spearman's rank correlation coefficient or Spearman's rho that symbolizes a parameter that represents the value of the linear correlation coefficient that would be computed by using ranks all of the paired data in the population for all statistics students.
r is estimated to be zero, since there's no correlation between body temperature and head circumference.
Step-by-step explanation:
Spearman's rank correlation coefficient or Spearman's rho is a nonparametric measure of rank correlation
Answer: a. Number of visitors
b. average() amount spent per person by visitors to the park
c. Yes , we know the average amount spent per person byvisitors to the park. It is $28 per person.
Step-by-step explanation:
- A population is a group of all members according to the researchers's subject of interest.
- A parameter is a number that gives the measure of a factor generated from population (for ex Population mean () , population proportion (p) ).
- A sample is a finite subset of the population that represents the population in an analysis.
- A statistic is a number that gives the measure of a factor generated from sample (for ex sample mean () ,sample proportion () ).
For the given situation, A researcher wishes to estimate the average amount spent per person by visitors to a theme park.
Population by researcher's point of interest : "Number of visitors"
Parameter of interest : "average() amount spent per person by visitors to the park"
Since he takes a random sample of forty visitors and obtains an average of $28 per person.
Here , sample : forty visitors
And average amount spent per person by visitors to the park from sample :
$28 per person.
The sample means is the best point-estimate for the population mean.
So , the best point-estimate for average amount spent per person by visitors to the park here is $28 per person.
