- What is an experiment?I am working on my class project. I do not know how to explain Type I and Type II errors based on my data.An obstetrician wanted to know the effectiveness of two methods of relieving pain in women due for child delivery. Specifically, she wanted to see if there is a difference in the mean duration of active labor (in minutes) in women introduced to these methods. A total of 28 women were enrolled in the study with fourteen subjects receiving continuous epidural infusion (Group A), while the other fourteen received hourly intermittent epidural injection (Group B). The mean duration of active labor for Group A was 134.1 with a standard deviation 79.79 minutes while for Group B, it was 83.2 ± 46.01 minutes. Does this suggest that there is a difference in the effects of the two methods in terms of reducing the duration of active labor? Use an alpha of 0.05 for this scenario.
- The article "Teenage Physical Activity Reduces Risk of Cognitive Impairment in Later Life"+ describes a study of more than 9,000 women from Maryland, Minnesota, Oregon, and Pennsylvania. The women were asked about their physical activity as teenagers and at ages 30 and 50. A press release about this studyt generalized the results of this study to all American women. In the press release, the researcher who conducted the study is quoted as saying the following. Our study shows that women who are regularly physically active at any age have lower risk of cognitive impairment than those who are inactive but that being physically active at teenage is most important in preventing cognitive impairment. Answer the following four questions for this observational study. (a) What is the population of interest? O all teenage girls all women in Maryland, Minnesota, Oregon and Pennsylvania all women all women between 30 and 50 all American women (b) Was the sample selected in a reasonable way? O No,…Anterior cruciate ligament (ACL) injuries occur most frequently in planting and cutting sports such as basketball, soccer, and volleyball. National collegiate athletic association injury data show that female athletes injure the ACL more frequently than their male counterparts do. A sports medicine professor wants to test this claim. He surveyed 5 universities that had both men's and woman's basketball, soccer, and volleyball and asked them how many grade 3 ACL tears they had during the past 5 seasons. Using the following results, are women at greater risk than men for ACL injuries? (use a standard deviation of 0.01, one tail test). Women- 4,3, 5, 2,4 Men- 2, 0, 1 ,2, 1 Calculate the pooled variance for the data.Anterior cruciate ligament (ACL) injuries occur most frequently in planting and cutting sports such as basketball, soccer, and volleyball.

But under the conditions of pandemic like this is suspected to be a change to water consumption in households.A researcher surveyed and sampled 12 household heads and was asked about the use of gallon water. As for the data obtained are as follows 51, 8, 13, 17, 13, 15, 12, 13, 15, 16, 9, 7. If it is known that the data is distributed normal. Use a significance level of 5% test whether the average household water use is increasing (greater than 10 gallons)? What will happen if water use in these households increases 5% from before?If the difference in means of two data sets is not zero, does that imply that on average the two variables are significantly different?
