The answer is:
The slope is: 4
The y-intercept is: 3
The explanation is shown below:
1. The slope intercept form of the linear equation is:
Where is the slope and
is the y-intercept.
2. Therefore, you must solve for <em>y</em>, as following:
Answer:
The 95% confidence interval for the true proportion of all teams that had a season winning percentage better than 0.500 is (0.1853, 0.6147).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence interval
, 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:
8 out of the 20 teams in the sample had a season winning percentage better than 0.500. This means that .
95% confidence interval
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 95% confidence interval for the true proportion of all teams that had a season winning percentage better than 0.500 is (0.1853, 0.6147).
