Answer: test statistic = 0.002
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 = 15
For the alternative hypothesis,
µ > 15
The inequality sign means that it is right tailed.
Since the population standard deviation is not given, the distribution is a student's t.
Since n = 36,
Degrees of freedom, df = n - 1 = 36 - 1 = 35
t = (x - µ)/(s/√n)
Where
x = sample mean = 16.33
µ = population mean = 15
s = samples standard deviation = 2.54
t = (16.33 - 15)/(2.54/√36) = 3.14
We would determine the p value using the t test calculator. It becomes
p = 0.002
Answer:
Step-by-step explanation:
domain represents the numbers at the x endpoints of a graph.
on the graph we see that on the left, the line ends when x is -4
on the right, the line ends when x is 4
the domain is
-4, 4
but notice how on the left there is an open circle
this will be written with a parentheses
( -4, 4
and notice how on the right there is a closed circle
this will be written with a bracket
(-4, 4]
so the answer is C
