Suppose we measure GPA for people in our class, we find the mean is 2.8 and the median is 3.2. What can you say is most likely true about GPAs in our class?

In the population of students at Milpitas High School, the proportion who are in the marching band is 0.10. In a random sample of 100 students from this population, the proportion who are in the marching band is 0.04. We would call the value 0.04 a A. statistic. B. parameter. C. z-score. D. P-value. E. significance level.

Gaining admittance into medical school is a difficult task. Researchers want to know if more students who complete a graduate degree gain admission into medical school than those who do not. They compare the number of students who were admitted who had a master's degree with those who did not. A detailed analysis of the data is carried out to arrive at a conclusion. What type of a research study is this? O a survey O an experiment O an observational study O a controlled study
Listed below are pulse rates (beats per minute) from samples of adult males and females. Find the mean and median for each of the two samples and then compare the two sets of results. Does there appear to be a difference? Male: 90 53 58 83 62 54 59 70 61 73 57 67 53 96 69 Female: 91 85 93 85 81 88 88 87 94 72 67 86 80 79 77 Find the means. The mean for males is beats per minute and the mean for females is beats per minute. (Type integers or decimals rounded to one decimal place as needed.)
On average, a sample of n = 36 scores will provide a better estimate of the population mean than a sample of n = 49 scores from the same population.
Mary is running for mayor. She wants to know if she has a chance to win, so she collects a random sample of 40 citizens to see if they are going to vote for her of her opponent, Henry. Out of the 40 citizens who were asked, 24 said they were voting for Henry and the other 16 said they were voting for Mary. Using this data test H0: p=.5 vs. Ha: p>.5, where p is the true proportion of people, who will vote for Mary in the population (i.e., the entire town)? Find the p-value of this test, and what is your conclusion if the test is performed at the a=.5 level?
