The answer would be 10^-3
Answer:
THIS KID DON'T MAKE NO SICES
Step-by-step explanation:
Answer:
The test statistic would be given by:
(1)
And replacing we got:
Step-by-step explanation:
Information given
represent the sample mean
represent the sample standard deviation
sample size
represent the value that we want to test
t would represent the statistic
System of hypothesis
We want to test if the true mean is lower than 25, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The test statistic would be given by:
(1)
And replacing we got:
Solution for 3n-2=15+3n equation:
Simplifying
3n + -2 = 15 + 3n
Reorder the terms:
-2 + 3n = 15 + 3n
Add '-3n' to each side of the equation.
-2 + 3n + -3n = 15 + 3n + -3n
Combine like terms: 3n + -3n = 0
-2 + 0 = 15 + 3n + -3n
-2 = 15 + 3n + -3n
Combine like terms: 3n + -3n = 0
-2 = 15 + 0
-2 = 15
Solving
-2 = 15
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
