Assuming the equation reads:
Add 16 to both sides:
Multiply both sides by 5 to get rid of the denominator and to get x by itself:
The value of x will be
70.
Step-by-step explanation
The answers in bold is what was required from the question.
the null hypothesis using symbol:-
H₀ : μ = 11.80
the alternative hypothesis using symbol:-
H₁: μ ≠ 11.80
This is a one tailed test. Given what you know, you will evaluate this hypothesis using a t test statistic.
Alpha level = 0.05
Sample size = n
Degree of freedom = n-1 = 40-1 = 39
To use the t distribution we will have to find the critical value from the t table this value is 1.685
But the question does not have sample mean and sample standard deviation. So I was unable to solve for the standard error

Answer:
It is better to be paid $7.50 dollars per hour
Step-by-step explanation:
Since 24 hours is a day, and 7 days is a week, we will do 24 x 7 which equals 168, then we do 168 x 7.50 which gives us an outstanding amount of $1,260, and that is obviously better than $300 dollars, hope this helped!
