1. Independent random samples of students were taken from two high schools, R and S, and the proportion of students who drive to school in each sample was recorded. The difference between the two sample proportions (R minus S) was 0.07. Under the assumption that all conditions for inference were met, a hypothesis test was conducted where the alternative hypothesis was the population proportion of students who drive to school for R was greater than that for S. The p-value...
High School Band ~ In most US high schools, students can play an instrument in three types of bands. A random sample of high school band students was taken and the results are summarized in the table below.

Rarely eat 3 meals a day Usually eat 3 meals a day 16 Male 32 65 Female 26 Is there any evidence that the proportions falling into each of the 2 categories are not the same for males or females? Test the relevant hypotheses with a =...

suomi A random sample of female students at a local university was selected. Each student reported her height (in inches), and then her height was actually measured. The results were as follows. 64 Reported height 62 66 67 61 69 60 63 68 65 70 Measured height 618 64.7 67 63.8 59.469.8 59.4 61.766.3 64.1 71.3 Difference 0.2 1.3 0 0.2 1.6 -0.8 0.6 1.3 1.7 0.9 -1.3 At the 0.10 level of significance, can we conclude (by using the...
A study was designed to compare the attitudes of two groups of nursing students towards computers. Group 1 had previously taken a statistical methods course that involved significant computer interaction. Group 2 had taken a statistic methods course that did not use computers. The students' attitudes were measured by administering the Computer Anxiety Rating Scale (CARS). A random sample of 16 nursing students from Group 1 resulted in a mean score of 41.3 with a standard deviation of 2.5. A...
