Answer:
H0: p = 0.078
Ha: p ≠ 0.078
Step-by-step explanation:
The researchers say that the rate is about 7.8%, or 0.078 as a decimal. That makes that the null hypothesis because using "is" in math is the same as saying "equals" and the null hypothesis always has the statement of equality in it. The reason there is a not equals to sign in the alternate is for this reason as well. The researchers say it is about that amount, not more or less than that amount. So it makes this a 2 tailed test. If the amount is significantly higher or lower, then we might have to reject the null hypothesis depending on the outcome of the test.
To solve this problem you can make a rule of three and find the percentage of increase
113 ---> 100
163 ---> x
Clearing x we have
x = (163/113) * (100) = 144.25
Then, the percentage of growth is
144.25-100 = 44.25
answer
the approximate percentage increase of the number of seats in the theater 44.25%

Answer:
$10.52 tip should be given to the waiter.. The total bill including tax is $67.33
Step-by-step explanation:
We are given the following in the question:
Pre-tax amount = $52.60
Tip percentage = 20%
Tax percentage = 8$
Tip value =
Thus, $10.52 tip should be given to the waiter.
Tax value =
Total bill =
Pre tax amount + Tip + Tax
Thus, the total bill including tax is $67.33
