Dwight spent $250 to rent a jet ski for 6 hours. The rental company charges a base rate of $150 for the first two 2 hours, and t
1 answer:
Each additional hour or rental costs $25.
Step-by-step explanation:
Given equation is;
4h+150=250 Eqn 1
Where 150 is the cost for first 2 hours and 4h is the cost for remaining hours.
Total cost = $250
Solving Eqn 1
Subtracting 150 from both sides
Dividing both sides by 4
Each additional hour or rental costs $25.

Answer:
We conclude that the population mean is 24.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 24
Sample mean, = 22.8
Sample size, n = 100
Alpha, α = 0.05
Sample standard deviation, s = 8.3
First, we design the null and the alternate hypothesis
We use Two-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
We calculate the p-value with the help of standard z table.
P-value = 0.1498
Since the p-value is greater than the significance level, we accept the null hypothesis. The population mean is 24.
Now,
Since, the z-statistic lies in the acceptance region which is from -1.96 to +1.96, we accept the null hypothesis and conclude that the population mean is 24.
