Ed has x+100

(x+100)-20=5x

x+100-20=5x

x+80=5x subtract x from each side

x-x+80=5x-x

80=4x divide each side by 4

x=20 (amount that Robert has)

x+100=20+100=120 dollars (amount that Ed has)

120-20=5*20

100=100

<h3>What takes place if a sample size is not big enough? </h3>
  • When a sample size taken by a person or a researcher  is not big or inadequate for the alpha level and also analyses that one have chosen to do,  it will limit the study statistical power.

Due to the above, the ability to know a statistical effect in one's sample if the effect are present in the population is greatly reduces.

See full options below
