Answer:
Yes
We fail to reject the alternative hypothesis Hₐ < 30, that is the average age of students is less than 30
Step-by-step explanation:
Yes because, there is an average age of a sample which can be tested against a null hypotheses
We put
Null hypothesis as H₀ = 30
The alternative hypothesis as Hₐ < 30
We have
With
= 29
μ = 30
σ = 5.2
n = 65
α = 10%
We have
Here we have z = -1.55 and critical z = -1.28
Which gives a critical of 29.83 with the probability P = 0.061 < 0.1 Hence we reject the null hypothesis as there is sufficient evidence to suggest that the average age is less than 30 years.
Answer:
from day 0 to day 8 after the strawberries first ripen.
Step-by-step explanation:
From inspection of the graph, the profit increases from day 0 to day 8 after the strawberries first ripen.
The profit starts to decline after 8 days.
The maximum profit is on day 8
So in order to determine the factors of the given expression above, here is the step by step process.
Firstly, we need to know the factors of -8 that when multiplied together will result it -8. So after, I have listed it, I found out that it is -2 and +4.
So let us check. So the factors for this would be (3x-2)(x+4). When you multiply these factors, the result would be <span>3x2 + 10x - 8. Hope this answer helps.</span>
The correct answer is 0.6 meters. Since it takes 10 decimeters to make 1 meter, just divide 6 by 10 to see how many sets of 10 go into 6 decimeters. When you divide by 10, just move the number one place over to the right. By doing this, we get that 6 / 10 = 0.6, so 6 decimeters = 0.6 meters.
Hope this helps!
