Answer:
<h2>1. (52 - 2) (1 + 1) = 100</h2><h2>2. (12 - 2) (9 + 1) = 100</h2><h2>3. (6 - 2) (24 + 1) = 100</h2><h2>4. (3 - 2) (99 + 1) = 100</h2><h2>5. (102 - 2) (0 + 1) = 100</h2>Step-by-step explanation:
<h3>1. let r= 52 and s= 1</h3><h3>(52 - 2) (1 + 1) = 100</h3><h3>50 × 2 = 100</h3><h3 /><h3>2. let r= 12 and s= 9</h3><h3>(12 - 2) (9 + 1) = 100</h3><h3>10 × 10 = 100</h3><h3 /><h3>3. let r= 6 and s= 24</h3><h3>(6 - 2) (24 + 1) = 100</h3><h3>4 × 25 = 100</h3><h3 /><h3>4. let r= 3 and s= 99</h3><h3>(3 - 2) (99 + 1) = 100</h3><h3>1 × 100 = 100</h3><h3 /><h3>5. let r= 102 and s= 0</h3><h3>(102 - 2) (0 + 1) = 100</h3><h3>100 × 1 = 100</h3>Given:
Standard error = 4
Population standard deviation = 16
To find:
The value of n.
Solution:
The formula of standard error is:
Where, SE is standard error , is population standard deviation and n is the total number of elements.
Substituting in the above formula, we get
Taking square on both sides, we get
Therefore, the value of n is 16.
