The Nellie Mae organization conducts an extensive annual study of credit card usage by college students. For their 2004 study, they analyzed credit bureau data for a random sample of 1413 undergraduate students between the ages of 18 and 24. They found that 76 % of the students sampled held a credit card. Determine a 95% confidence interval for the proportion of all undergraduate college students in the United States who held a credit card in 2004.(4 decimals)

A second-semester junior at a large high school wants to estimate the number of colleges a senior applies to on average before deciding where they will attend. The junior randomly selects 19 seniors and asks them how many colleges they applied to and records the number. Use the data below to construct a 99% confidence interval to estimate the true mean number of colleges seniors at this school apply to before deciding about which college to attend. 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 6, 7, 7, 8, 9 3. Do. Use technology to find the mean and standard deviation of the sample. Round each answer to 2 decimal places. Use those values and t* from the table to calculate the confidence interval. Round the endpoints to 1 decimal place. 99% confidence interval is (, )
Several years ago, 42% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,185 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,185 surveyed, 499 indicated that they were satisfied. Construct a 90% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed. find the 90% confidence interval.

Example: You would like to construct a 90% confidence interval for the proportion of graduating seniors that go directly on to graduate school. You randomly sample 386 graduating seniors and find that 73 will be enrolling in graduate school in the upcoming semester. 1. What is your point estimate? 2. Construct a 90% confidence interval for the true proportion of graduating seniors that go directly on to graduate school? 3.How many graduating seniors will you have to sample to have a margin of error within 2%?
