Answer:
Hence the correct option is the distribution with n = 225 will have a smaller standard error.
Step-by-step explanation:
Now the standard deviation is
If n = 100 then consider
.
If n= 225 then consider
.
Here the distribution with n = 225 will have a smaller standard error.
Answer:
Step-by-step explanation:
<u>Use the ratio of corresponding sides of similar triangles:</u>
- 25/x = x / 144
- x² = 25*144
- x = √25√144
- x = 5*12
- x = 60
