It’s the second one because if you look at the averages you can see no ruff stuff is more expensive so then you just do subtraction to find how much more expensive it is
Answer:
a. the Student's t-distribution with 124 degrees of freedom
Step-by-step explanation:
We have no information about the standard deviation of the population, just for the sample, which means that the student's t-distribution is used.
Degrees of freedom
Sample size subtracted by 1.
125 households were sampled.
125 - 1 = 124 degrees of freedom.
So the correct answer is:
a. the Student's t-distribution with 124 degrees of freedom
Answer:
(-6, 3)
Step-by-step explanation:
The function f(x) = a |x − h| + k has its vertex at (h, k).
In this case, the vertex is (-6, 3).
The answer is 23 I took the test
Answer:
The probability of not spinning a 5, flipping heads, then spinning a 1 is 0.08
Step-by-step explanation:
I may assume the spin contains 5 numbers ( plz change and recalculate if the no. of numbers is different)
P(not spinning a 5) = 4/5
P(flipping head) = 1/2
P(spinning 1) = 1/5
P(not spinning a 5, flipping heads, then spinning a 1)= 4/5 * 1/2 * 1/5 = 0.08 = 0.1
