Answer:
Open ended investigation
Explanation:
The above is an example of an open ended investigation. In understanding what an open ended investigation is, we first of all need to understand what open endedness means. Open endedness means whether one solution or answer is possible. In other words it means that there may be various ways and alternatives to solve or answer a question or bring solution to an investigation.
From the definition, we can deduce that an open ended investigation is a practical investigation that requires students to utilize procedural and substantive skills in arriving at conclusion through evidence gathered from open ended research or experiment(as in not close ended, not limited to ready made options, freedom to explore all possibilities). This is seen in the example question where students are asked to explore the different examples of physical controls and displays and also discuss their observations. Here students are not required to produce a predefined answer but are free to proffer their own solutions

Answer:
1) 402.7 grams. This estimate is called the sample mean.
2) (399.11, 406.29)
3) The 99 percent confidence limits is between 399.11 grams and 406.29 grams.
I am 99% sure that the value lies between 399.11 grams and 406.29 grams.
Explanation:
sample size (n) = 40, the mean weight (x)= 402.7 grams and the standard deviation (σ)=8.8 grams
1) The point estimated mean weight of the population is 402.7 grams. This estimate is called the sample mean.
2) c = 99% = 0.99
α = 1 - 0.99 = 0.01
.
The z score of 0.005 corresponds with the z score of 0.495 (0.5 - 0.005).
.
The margin of error (e) = 
The confidence interval = x ± e = 402.7 ± 3.59 = (399.11, 406.29)
3) The 99 percent confidence limits is between 399.11 grams and 406.29 grams.
I am 99% sure that the value lies between 399.11 grams and 406.29 grams.
Answer:
import java.util.Scanner;
public class num2 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter Name");
String name = in.next();
System.out.println("Enter Age");
int age = in.nextInt();
System.out.println("The age of "+name +" is "+age);
}
}
Explanation:
Java programming language is used to write the code.
The scanner class is used to prompt and receive values for name and age which are stored in the appropriate variables.
The key idea here is using string concatenation in the output statement in order to print the desired output
It would be the last one, because she isn't recording any type of data over what she is doing and she isn't observing it at all. She simply trimmed the stems of a bouquet of flowers. However, the other options insist that they are recording data and observing, like you would do when performing an experiment. I hope this helps! :)
