The first step for solving this equation is to write 
in exponential form with a base of 5.
= 
Write
in exponential form with a base of 5.
= 
Since the bases on both sides of the equal are the same,, set the exponents equal.
2x + 4 = -4x
Move the constant to the right side of the equation and then change its sign.
2x = -4x - 4
Now move the variable to the left side and change its sign.
2x + 4x = -4
Collect the terms with an x variable.
6x = -4
Lastly,, divide both sides of the equation by 6 to get your final answer.
x =

Replacing the info given we got:
And the p value would be given by:
Step-by-step explanation:
Information given
n=200 represent the random sample taken
X=12 represent the potatoes with major defects
estimated proportion of potatoes with major defects
is the value that we want to test
z would represent the statistic
represent the p value
Hypothesis to test
We want to check if the true proportion is less than 0.10 so then the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
