Answer:
Step-by-step explanation:
The null hypothesis is the statement or claim that is believed or assumed to be true. In this case, the null hypothesis is "They believe that 40% of first-time borrowers take out smaller loans than other borrowers". Since we are dealing with proportion, we will denote it with p. The null hypothesis would be
p = 0.4
The alternative hypothesis is what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected. The alternative hypothesis is "They perform a hypothesis test to determine if the percentage is the same or different from 40%". It would be written as
p ≠ 0.4
Answer:
12.5
Step-by-step explanation:
If the number of workers injured in each accident is independent of the number of accidents that occur, then the expected number of workers injured in a week equals the expected number of accidents per week times the expected number of workers injured in each accident.
But the expected number of workers injured in each accident is precisely the average or mean, so
Expected number of workers injured in a week = 5*2.5 = 12.5.
Or in other words, in 10 weeks there will probably be 125 workers injured.
The expected number of workers injured in a week at the industrial plant is 12.5, calculated by multiplying the expected number of accidents per week (5) by the expected number of workers injured per accident (2.5).
The expected number of accidents at an industrial plant per week is given as 5 and the mean number of workers injured per accident is given as 2.5. As the number of workers injured per accident is stated to be independent from the number of accidents that occur, we can merely multiply the two expected values to find the overall expected value of workers injured in a week.
So, Expected number of workers injured per week = Expected number of accidents per week * Expected number of workers injured per accident = 5 * 2.5 = 12.5.
This implies that, on average, we can expect 12.5 workers to be injured at the industrial plant per week.

Answer:
a)
b) 150min
Step-by-step explanation:
a) Using the formula for colony growth we need to find the specific value of k, to do this you'll use the time, initial and final number of colonies provided in your problem.
b) Once we have our expression we only have to use our final and initial number of bacteria to find t.
I hope you find this information useful! good luck!
Answer:
The domain of f(x) corresponds to the set of real numbers.
D f(x) ∈ ∀X; D f(x) ∈ R
Step-by-step explanation:
f(x)=X+18-3X-15
f(x)=-2X+3 (right line with negative slope)
This function exists for all values of X, so the domain corresponds to the set of real numbers.
D f(x) ∈ ∀X; D f(x) ∈ R
