Answer:
isabella will be able to pay 2 full years of insurance with her remaining savings
Step-by-step explanation:
as we know isabella saved $13,000
the car cost $11,675 - so subtracting that from her total we will know that she has: $1,325 remaining
insurance for a year costs $650,
so we will divide her remaining sum by the yearly cost giving us -
1,325/650
= 2.0.3....
this means that she will be able to pay for 2 full years of insurance with her remaining savings
hope this helped:)
Answer:
the most conservative hypothesis is
<em>H₀</em>: <em>p</em> = 0.18, <em>Hₐ</em>: <em>p</em> > 0.18.
Step-by-step explanation:
The researcher wants to test whether the rate of smoking among adults in Chicago is greater than the national rate of 18% or not.
The hypothesis for this test can be defined as follows:
Null Hypothesis (
): The rate of smoking among adults in Chicago is same as the national rate, i.e. <em>p</em> = 0.18.
Alternate Hypothesis (
): The rate of smoking among adults in Chicago is greater than the national rate, i.e. <em>p</em> > 0.18.
So the most conservative hypothesis is <em>H₀</em>: <em>p</em> = 0.18, <em>Hₐ</em>: <em>p</em> > 0.18.
Answer: option A
Step-by-step explanation: We can only make a conclusion regarding this question by picking a level of significance.
Hence I will assume a 5% level of significance, that's α = 0.05.
If p > α, it simply means that we have a high chance of committing a type 1 error (because α is the probability of committing a type 1 error), hence we reject the null hypothesis meaning it is wrong.
If p < α, it means that we have a very low chance of committing a type 1 error hence we accept the null hypothesis because it is right.
Note even if we decide to try any reasonable value of α, we will come to the same conclusion made above.
The answer is 9/35
