We wish to estimate (with 95% confidence) what percent of
students take the bus to school. We survey a random sample of 850
students and get the following results:
70 students take the bus, 770 students do not take the bus and 10
students did not respond
We should use:
- 2-SampTInt
- TInterval
- 2-PropZInt
- ZInterval
- 1-PropZInt
- 2-SampZInt
Homework Answers
Here, sample size is given 850
Out of 70 students take the bus to school
Here, we need to find proportion
So, answer is 1 propZInt

we wish to estimate μ, the mean length of the fish in our pond. we take a random sample of 65 fish and measure their lengths. for this sample, we find an average length of 4.53 cm, and a standard deviation of 0.8cm. i) using our observations as a pilot study, determine the sample size needed to estimate the mean μ within 0.1cm with 95% confidence. ii) find the upper confidence interval for μ

We wish to survey students at community college campuses to find out what percent of them prefer taking online classes. We want 95% confidence, and we want the sample percentage to be within 5 percentage points of the population percentage. How large a sample do we need? Round up to the nearest integer (for example, 92.15 would be rounded up to 93).

Consider a population having a standard deviation equal to 9.96. We wish to estimate the mean of this population. (a) How large a random sample is needed to construct a 95% confidence interval for the mean of this population with a margin of error equal to 1? (Round your answer to the next whole number.) The random sample is units. (b) Suppose that we now take a random sample of the size we have determined in part a. If we...

We want to estimate the mean weekly earnings of students at a particular college with 95% confidence. How many students must be randomly selected so that the sample mean is within $1 of the population mean? Population standard deviation is known to be $10.

1. We are formulating a 95% confidence for the mean of a random variable. We take a random sample size=11. This random sample exhibits a sample mean of 346 and a sample standard deviation of 78. What will the value of our upper interval be?

A school administrator claimed that the average time spent on a school bus by those students in his school district who rode school buses was 35 minutes. A random sample of 20 students who did ride the school buses yielded an average of 42 minutes riding time with a standard deviation of 6.2 minutes. Does this sample of size 20 contain sufficient evidence to indicate that the mean riding time is greater than 35 minutes at the 5% level of...

The survey also asked participants for their level of education, and we wish to estimate the difference in the proportion to use online dating between those with a college degree and those with a high school degree or less. The results are shown in the two-way table below. College High School Total Yes 157 70 227 No 666 565 1231 Total 823 635 1458 Let group 1 be the proportion of college graduates using online dating and group 2 be...

9) A researcher wishes to estimate, with 95% confidence, the population proportion of students who did not change their major. Her estimate must be accurate within 2.5% of the true proportion. a) What is the minimum sample size needed assuming that no prior information is available? b) What is the minimum sample size needed using a prior study that found that 34% of the students did not change their major?
