When using technology you must attach all relevant outputs to your assignment. 1. Below are 18 scores randomly selected from Professor Mahar's bowling scores. 148, 217, 182, 192, 192, 191, 204, 234, 179, 247, 199, 183, 171, 194, 214, 205, 215, 193 Construct a 95% confidence interval on the median of Professor Mahar's bowling scores Conduct a 95% confidence hypothesis...
Question 1. Thirty graduate students were asked how many credit hours they were taking in the current quarter. Download the available data: Calculate the mean, median, standard deviation, variance, and range for this sample using Excel. Write a sentence explaining what each measure means. What is the standard error of the mean based on the data? What would be the best point estimate for the population credit hours? (“Population” refers to all graduate students’ credit hours in the universe.) What...
You roll a six-sided die. Find the probability of each of the following scenarios. (a) Rolling a 6 or a number greater than 3 (b) Rolling a number less than 4 or an even number (c) Rolling a 4 or an odd number (a) P(6 or number> 3)- (Round to three decimal places as needed) (b) P/1 or 2 or 3 or 4 or 6)-( Round to three decimal places as needed.) (c) P(4 or 1 or 3 or 5)...
MAT 107 Project: Age of Students in College Professor Sumner Collect Data: (5 points) You will need to ask 30 college students their age. The students can attend any college or university. Use the table below to input the data you collected. If you do the work for this project by hand, you must show the work you do to arrive at your results to earn full credit. If you use technology (computer, calculator, etc.) to obtain the results, you...
DIRECTIONS: Make sure your responses are neat and readable. You must show me your calculation in a separate piece of paper. Homework that is difficult to grade due to messiness will be returned ungraded. If you would like to get full credit, do not forget to attach the Excel output. The number of hours 10 students spent studying for a test and their scores on that test is represented in the table below. 0 2 4 5 5 Hours spent...
Can someone please check my work? If I made an error can you please correct me and show me the steps of how to get there?

Question 2 (7 parts, 25 marks) Following your initial analysis in Question 1 above, you think that, in addition to cannabis use, road conditions may also affect driving abilities and contribute to an increased risk of road accidents. You suggest that further testing be made using 5 different road-condition scenarios in the virtual driving simulator. Your proposal is accepted and a new group of 60 individuals are solicited to participate in the study and are randomly assigned to one of...
photos for each question are all in a row (1 point) In the following questions, use the normal distribution to find a confidence interval for a difference in proportions pu - P2 given the relevant sample results. Give the best point estimate for p. - P2, the margin of error, and the confidence interval. Assume the results come from random samples. Give your answers to 4 decimal places. 300. Use 1. A 80% interval for pı - P2 given that...
ntroduce your scenario and data set. Provide a brief overview of the scenario you are given above and the data set that you will be analyzing. Classify the variables in your data set. Which variables are quantitative/qualitative? Which variables are discrete/continuous? Describe the level of measurement for each variable included in your data set. Discuss the importance of the Measures of Center and the Measures of Variation. What are the measures of center and why are they important? What are...
