The range of set B is approximately the range of set A
Answer:
Null Hypothesis
H₀ : P = 3.8
Alternative Hypothesis
H₁: P > 3.8
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<u><em>Null Hypothesis</em></u> :-
The single statistic, H₀ will be that the sample statistic
H₀ : There is does not differ significantly from hypothetical parameter values
H₀ : P = 3.8
<u><em>Alternative Hypothesis:</em></u>
The statistic , H₁ will be the sample statistic
H₁: There is differ significantly from hypothetical parameter values
H₁: P > 3.8
Multiply bath sides by (-13)
Step 1:(-13).a/(-13) <= -16(-13) ===> . Mistake since she the < sign into >
Step 2: a<=208 is the right answer
Step 3: The line should go from 208 to the left & not to the right
Answer:
The 99% confidence interval for the proportion of athletes who graduate is (0.5309, 0.7323).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
For this problem, we have that:

99% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 99% confidence interval for the proportion of athletes who graduate is (0.5309, 0.7323).
