Why is it important to avoid a smaller sample size?

Mathematics

Nitella [24]2 years ago

Answer:The importance of sample size calculation cannot be overemphasized. A research can be conducted for various objectives. A smaller sample will give a result which may not be sufficiently powered to detect a difference between the groups and the study may turn out to be falsely negative leading to a type II error.

Can someone plz help me solved this problem! I’m giving you 10 points! I need help plz help me! Will mark you as brainiest!
Kobotan [32]

Answer:  $2 or $9

<u>Step-by-step explanation:</u>

Revenue (R) = $1800 , x = 1100 - 100p

R = xp

1800 = (1100 - 100p)p             <em>substituted x with 1100 - 100p</em>

1800 = 1100p - 100p²             <em>distributed p into 1100 - 100p</em>

100p² - 1100p + 1800 = 0       <em>added 100p² & subtracted 1100p</em> on both sides

     p² - 11p + 18 = 0                <em>divided both sides by 100</em>

(p - 2) (p - 9) = 0                     <em>factored quadratic equation</em>

p = 2  p = 9                         <em>applied Zero Product Property to solve for p</em>

Find the least common denominator for these two rational expressions 7/n^2 -8/7n
lianna [129]

Answer:

7n²

Step-by-step explanation:

7/n² - 8/7n

Least common multiple will be the least common denominator

L.C.M = 7n²

Dividing the L.C.M by denominators and multiplying with numerators;

((7×7) - (n×8))/7n²

= (49 - 8n)/7n²

7n² is the least common denominator
