Hello!
The range is all of the y-values of the function. As we can see, the function is at y-values 0, -2,-4 and -6.
Therefore, our answers are 0 ,-2 and -6.
I hope this helps!
Answer:N10500
Step-by-step explanation:
10%of 14000=1400
20%=1400x2=2800
5%=1400 divided by 2=700
25%=2800+700=3500
14000-3500=10500
hope this helps
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 17
For the alternative hypothesis,
µ < 17
This is a left tailed test.
Since the population standard deviation is not given, the distribution is a student's t.
Since n = 80,
Degrees of freedom, df = n - 1 = 80 - 1 = 79
t = (x - µ)/(s/√n)
Where
x = sample mean = 15.6
µ = population mean = 17
s = samples standard deviation = 4.5
t = (15.6 - 17)/(4.5/√80) = - 2.78
We would determine the p value using the t test calculator. It becomes
p = 0.0034
Since alpha, 0.05 > than the p value, 0.0043, then we would reject the null hypothesis.
The data supports the professor’s claim. The average number of hours per week spent studying for students at her college is less than 17 hours per week.
