Here are summary statistics for randomly selected weights of newborn girls: n= 36, x= 3222.2 g, s=686.7 g. Use a confidence level of 90% to complete parts (a) through (d) below. a. Identify the critical value t12 used for finding the margin of error. (Round to two decimal places as needed) b. Find the margin of error. E=9 (Round to one decimal place as needed.) Question Viewer c. Find the confidence interval estimate of p. (Round to one decimal place as needed.) d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. O A. One has 90% confidence that the sample mean weight of newborn girls is equal to the population mean weight of newborn girls O B. One has 90% confidence that the interval from the lower bound to the upper bound contains the true value of the population mean weight of newborn girls. OC. There is a 90% chance that the true value of the population mean weight of newborn girls will fall between the lower bound and the upper bound O D. Approximately 90% of sample mean weights of newborn girls will fall between the lower bound and the upper bound Activate Windows Statcrunch P Type here to search

Study A Use the following description of a research study to answer the next five questions. Researchers were were interested in promoting physical activity within the workplace. They recruited participants to join a team challenge encouraging ways to increase physical activity such as taking active breaks and taking the stairs. Participants either joined as a team or were assigned a team. These teams were then randomly assigned either to be the control group where they just received information about becoming more active or the team-building group, which received the same information as the control group but were encouraged to create a team name and bond as a team throughout the study. One outcome measure of the study was the number of flights of stairs that participants reported taking yesterday. Group Statistics Intervention Mean Std. Deviation Std.
