Answer:
- <u><em>Option b. just below 30%</em></u>
<u><em></em></u>
Explanation:
Please, see attached the <em>histogram that represents the distribution of acceptance rates (percent accepted) among 25 business schools in 2004. </em>
<em />
The<em> median</em> is the value that separates the lower 50% from the upper 50% of the data.
Since there are 25 business schools, the middle value is the number 13.
The height of each bar is the<em> frequency</em> or number of business school for that acceptace rate:
- The first bar has frequency of 1 school
- The second bar has frequency of 3 schools: cummulative frequency: 1+3=4.
- The third bar has frequency 5 schools: cummulative frequency 4 + 5 = 9.
- The fourth bar has frequency 3 schools: cummulative frequency: 9+3=12.
Then, the 13th value is on the next bar, the fifth bar.
The fifth bar has acceptance rates 25 ≤ rate < 30.
That means that the median acceptance rate is greater than or equal to 25 and less than 30.
Thus, the choice is the option <em>b. just below 30%.</em>
Answer:
a) 0.10425
b) 0.00475
c) 0.04975
d) 0
Step-by-step explanation:
a) Pr (the test result will be positive) = (0.95 ×
) + ( 0.10 ×
)
= 0.00475 + 0.0995
= 0.10425
b) Pr (positive result, the person is a sufferer) = 0.95 x ![\frac{0.5}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B0.5%7D%7B100%7D)
= 0.00475
c) Pr (negative result, non sufferer) = (1-0.95) x ![\frac{99.5}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B99.5%7D%7B100%7D)
= 0.04975
d) Pr ( person misclassified) = 0

You need to find the amount of miles per 1 gallon.
dived the number of miles over gallons.
will look like:
