A cognitive psychologist wants to know whether memory performance of older adults differ from younger adults. she randomly selects 24 elderly individuals and finds that their score on fa standardized memory test equals 553.2,. Scores on the standardized test in the population of younger adults are distributed normally with a mean equal to 497 and a standard deviation equal to 95.Is there sufficient evidence to conclude that memory performance differs between the two age groups ? Use significance level of 0.01 . State the null and alternative hypothesis for this scenario

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
