Answer:
We conclude that garbage collector's average picking is more than four tons of garbage per day.
Step-by-step explanation:
We are given the following information n the question:
First, we design the null and the alternate hypothesis
Significance level = 5% = 0.05
P-value = 0.04
- The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.
- P values evaluate how well the sample data support that the null hypothesis is true.
- P-value is a measure or indicator that helps us to know that whether the sample belongs to the population or not.
- Null hypothesis states that the sample belongs to the population.
- A high p-values states that the null hypothesis is true ad the sample belongs to the population.ll.
- A low p-value suggests that sample provides enough evidence that you the null hypothesis is not true and the sample does not belong to the population.
- We compare p-value to significance level to obtain our result.
Here,
p-value = 0.04 < Significance level = 0.05
Since the p-value is lower than the significance level, we fail to accept the null hypothesis and reject it. That is there were enough evidence to support the fact that sample does not belong to the population and we conclude that garbage collector's average picking is more than four tons of garbage per day.
The cost of the metals from the calculations performed is $ 402421.
<h3>What is density?</h3>Density can be explained as a quantity having mass per unit volume and this can be calculated as:
Mass of the metal = ?
Density of the metal = 7.3 g/cm^3
height of the metal = 610 cm
radius of the metal = 8.7 cm
Volume of a cylinder can be calculated by using the formular below:
And this can be used by inserting the given values which is
Then we can calculate the mass as :
Mass = (density * volume)
=Since the cost is $0.38 per kilogram, then 3657 Kg costs
;( 1059003kg * $0.38)
= $ 402421
