Answer:
The confidence interval has a lower limit of 0.546 and an upper limit of 0.675.
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 z-score that has a p-value of .
In 2017, a random sample of 154 individuals who graduated from high school 12 months prior was selected. From this sample, 94 students were found to be enrolled in college or a trade school.
This means that
90% confidence level
So , z is the value of Z that has a p-value of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The confidence interval has a lower limit of 0.546 and an upper limit of 0.675.
Martina runs 10.5 miles in 75 minutes
<em><u>Solution:</u></em>
Given that,
Martina runs 7 miles in 50 minutes
<em><u>Therefore, miles ran in 1 minute is:</u></em>
At the same rate how many miles will she run in 75 mins
<em><u>Thus, to find the miles ran in 75 minutes:</u></em>
Thus she runs 10.5 miles in 75 minutes
