A recent study of college students indicates that 30% of all college students had at least one tattoo. A small private college decided to randomly and independently sample 15 of their students and ask if they have a tattoo. Find the standard deviation for this distribution.

Select one:

4.50

1.77

3.55

3.15

Solutions

Expert Solution

Standard deviation = sqrt(np(1 - p))

                               = sqrt(15 * 0.3 * 0.7)

                              = 1.77

In a recent study, approximately 42.5% of college students had student loans. A researcher was interested in determining if the proportion of students that took out student loans differed by the field in which they were studying in. The following data below was collected on 865 college students in seven different fields of study. Test at α = 0.05 to determine if there are significant differences in the proportions of students that take out student loans for each of the...

According to the Institute for Students in Shackles, 70% of all college students in a recent year graduated with student loan debt.  The University of Florida reports that only 52% of its graduates from a random sample of 500 students have student loan debt. Use a hypothesis test to determine if there is enough evidence to support UF’s claim that student loan debt is less. a) State your null and alternative hypothesis. b) Find p-hat, SD, Z, and the P-value

A recent study claimed that at least 15% of junior high students are overweight. In a sample of 160 students, 18 were found to be overweight. At α = 0.05, test the claim. Identify the claim, state the null and alternative hypotheses, find the critical value, find the standardized test statistic, make a decision on the null hypothesis (you may use a P-Value instead of the standardized test statistic), write an interpretation statement on the decision.

The student academic group on a college campus claims that freshman students study at least 2.5 hours per day, on average. One Introduction to Statistics class was skeptical. The class took a random sample of 30 freshman students and found a mean study time of 137 minutes with a standard deviation of 45 minutes. At α = 0.01 level, is the student academic group’s claim correct? Calculate the p-value.
