Answer:
there is no backgroung information?
Step-by-step explanation:
Answer:
Slope = -2/2 = -1
x-intercept = 6/1 = 6
y-intercept = 6/1 = 6
I wasn't sure what you really were asking for, so I did slope, x, and y.
Answer:
I am not sure but i will say C.
Step-by-step explanation:
Answer:
The first one is x axis
the second one is the axis
third one doesn't seem to be a reflection
Answer:
We reject the null hypothesis and accept the alternate hypothesis. Thus, it be concluded that the population mean is less than 20.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 60
Sample mean,
= 19.5
Sample size, n = 60
Alpha, α = 0.05
Population standard deviation, σ = 1.8
First, we design the null and the alternate hypothesis
We use One-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, it be concluded that the population mean is less than 20.
