3:1 because she makes 3 times more baskets than John.
If a bowl of fruit contains 8 lemons and 6 oranges, then the ratio of oranges to lemons is eight to six or 8:6 which then can be reduced by to 4:3.

Hope that is the answer you seek.
Answer:
The 68% confidence interval for the population proportion of college seniors who plan to attend graduate school is (0.16, 0.24).
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 .
A recent survey showed that among 100 randomly selected college seniors, 20 plan to attend graduate school and 80 do not.
This means that
68% 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 68% confidence interval for the population proportion of college seniors who plan to attend graduate school is (0.16, 0.24).
